Hunting Singletrack

by SS at
2:57 pm on Thursday 25th March 10
[bushcamp11, dirt, tanzania]

(Or The Day Everybody Got Flats)

After a fast stretch to Dodoma yesterday, the capital city of Tanzania, and a brief taste of beautiful pavement, I vowed to take today's stage slowly in order to let my body recover. My saddle sores have resurged with a vengeance, not that painful but if they get any worse, I may be back to a situation similar to Egypt.

Having been passed by most of the fast people and sweating heavily in the swampy morning humidity, I was already irritable when I hit a piece of corrugation that gave the final blow necessary to snap my bottle cage damaged in the truck collision. It's held on with two (red) allen bolts and snapped just below the top bolt. Hopefully this means it should be repairable with Duck tape but an annoyance until then anyhow. At the same time, my camera flipped around and pulled down on the earphone cable, yanking the left earphone down and out. Consequently, I'm now back to mono (probably better for road safety).

The day got better though, I caught up with Dave and Adam and rode with Adam down some singletrack running alongside the road. (For non cyclists - singletrack is the holy grail of mountain biking, a smooth, flowing path wide enough for just a single bike.) I've been dreaming of singletrack since we started cycling in January and increasingly as both the road sections bored me slightly and as the dirt sections seemed to lack genuine enjoyment. This singletrack was sublime, flowing, sandy and lacking corrugation like the road. On my fat but skinny tyres, I struggled a bit to avoid washing out around corners (where either wheel loses traction and the bike slides sideways).

At one point there was a rock in the way, up which it was necessary to ride in order to continue down the singletrack. From one angle the rock was rideable, from another it was a sheer vertical face. The rock was hidden behind shrubbery and although I noticed Adam suddenly climb up nearly a metre, it still came as a shock to me and there was a sickening creak as my front wheel hit the part of the rock inbetween the rideable part and the vertical wall. Somehow, my bike made it up the rock and once again I wished for front suspension.

We got to lunch at 10:30, earlier than the last few days. Carrying on from lunch, we passed Steve, the youngest rider on the tour, dealing with a flat tyre. As we continued down the road, we pulled over to let a tractor pass and as it came nearer, it was clear that there was a bike skewered on the front of its fork. It all made sense when we could see Steve inside the cabin, squashed in with another five Tanzanians.

After a lengthy (warm) sode stop, a pleasant descent began, not too technical and not too steep either. Unfortunately, it was here where I got my first flat while riding on dirt (all previous have happened at camp) - I hit a sharp rock and it gouged my front tyre and tube. The front tube was my one surviving Slime filled tube and started spraying out green liquid all over my right shin. Slime is a brand of sealant that is meant to seal punctures once they happen. In this case though, either because of the location (Gerald reported a similar issue) or because of the size of the puncture, the tube didn't seal and I had to swap the tube.

By this time, I thought Adam would have continued on but when I reached the bottom, he was patching up a tube. Apparently he had a flat too and in the process of pumping up his patched tube, the valve fell apart. His spare tube had three punctures in it which he was busy patching. As further riders came past, they mentioned that quite a few others had punctures. Once we had sorted it all out, we headed down the road and managed to get to a beautiful section of singletrack.

Unfortunately, Adam's tube went flat again on this section. He repaired the fourth hole on the tube but the valve self destructed as he pumped it up. I left him behind here and went ahead. Unfortunately the singletrack didn't appear to rejoin the road and at one point when it was clearly going in the wrong direction, I cut right across several fields.

It worked and the road was under my tyres. However, both my tyres were covered in circular seeds with sharp 'teeth'. Pulling these out, I heard a hissing sound from the front tube but it seemed to be holding its air. I went on a few kilometres to find about ten riders sitting drinking soft drinks. Joining them, I was about to leave when I realised my rear tyre was completely flat. Pulling it out, I searched for a hole but couldn't find one. Putting it back in, I pumped it up and hoped that the pressure would last until camp, only 13 km away (apparently).

It didn't last. Every kilometre, I'd have to stop and pump it up and with 5 km (apparently) left to go, I decided to patch the tube since it was taking so long to pump it up each time. Once I'd dealt with the tyre, I checked the front and found that it was now also flat. Removing the tube, I patched it too and put it back together.

My patch job on the rear tyre wasn't great and it was losing its air. I managed to cycle another couple of kilometres before it was flat again. Giving up on patching it again (riding on tube with insufficient pressure had stressed the valve to the point of failure) I started walking the remaining three kilometres to camp. Shortly afterwards, the green Land Cruiser that has been supporting us came past with Adam inside, his bike was also irrepairably punctured. I gave them my bike and continued walking, although they mentioned that the distance was actually approximately eight kilometres.

By this time it was pushing 4pm and so I was already resigned to a ridiculously long stage time. Walking in the mid afternoon Tanzanian heat, it was refreshing not too attract too much attention from the locals (apparently they ignore pedestrians). A while later, I saw a local cyclist who I managed to convince (with a few Swahili words and lots of gesturing) to let me ride his bicycle. He sat on the back of the bike and I pedalled the remaining few kilometres to camp on his single speed bike with 20" wheels.

When I finally reached camp, after a ten hour day, the soup was cold and the light slowly fading. After Martin (our awesome Kenyan bike mechanic) trued my wheel, and dinner was served, I set about patching my tubes. The rear tube was wrecked but the front tube was salvageable with five more patches. I think these singletrack dreams will have to wait until my return home.

Does walking and stealing a bike still count as EFI?

Forget Northern Kenya

12:35 pm on Monday 22nd March 10
[bushcamp10, dirt, tanzania]

Today was more of the same unpaved roads as yesterday and overall more descent than ascent. For the manyth time on this trip, I caught myself desiring those brake levers which lie inline with the normal drop brake levers but are placed on the top of the handlebar. It is quite tiring to have to use the drop position for prolonged periods and my advice to future riders on a cyclocross bike would be to definitely bring those. (Paul, a returning rider who wasn't able to complete the tour last year, has added such levers to his bike in the interim year.)

There were a few moments going down the descent where I lost control. This was usually when my speed picked up over terrain rough enough to mean I couldn't process the road ahead fast enough and I realise that the road is approaching faster than I can react to it. In all of these cases I was able to gain control quickly, mainly by braking. A couple of times while in this mode my hands flew off the bars as my bike hit protruding rocks and I had to struggle to regain my grip. This is a recipe for danger and my brakes are usually partially enabled whilst descending most hills on dirt.

My once pristine bottle, new in Nairobi, is now a mess - scraped and blackened, having been ejected from its home in my bike's bottle cage as my bike and I ride over rough terrain. These ejections are quite an exciting sight, the bottle usually bounces just once before settling with a resounding THWACK. As it settles, the lid usually pops off, flying several metres off across the road. The contents of the bottle, usually red energy drink, empty themselves onto the road in the shape of a flame from the mouth of the bottle. Normally I notice fairly quickly but when this happened for the third time today, I noticed after a 50 metre (vertical) descent and was preparing to walk back up the hill when another rider, Paul, appeared at the top. Pausing to pick up my bottle, he delivered it to me at the bottom = much appreciated!

It was cloudy this morning which meant breaking out the yellow sunglass lenses (increased definition of the road in lower light). The clouds usually mean increased humidity and I was definitely sweating intensely, drinking 7.5 litres of water the entire day (similar to our days in Sudan). There was nearly as much climbing as yesterday - another sweat inducing way to spend the day.

The northern Kenyan road is meant to be the toughest unpaved road of the trip but I'd like to contend that observation. Whilst most of the last couple of days have been relatively straightforward rocky double track, the Tanzanian road today had several severely sandy sections. The road in Kenya was tough but rideable and occasionally fun. This road was not fun, did not cause any adrenalin release and it was extremely hard work. At times, the sand was multiple inches thick, swallowing your tyre. At some points, forward motion was almost impossible and most riders had to dismount (having been forced to by the sand stopping their bikes) and walk for a few metres to find somewhere more steady to push off on.

The worst part of it was that it was at the end of the day. Usually you can push through sand but it requires a lot of energy. At the end of the third day, the day after a mando-day (which was actually easier than today's ride), there was no energy left. Camp was a welcome relief today and I genuinely fear for my EFI status if the road tomorrow is similarly sandy.

(You should note that the road hasn't always been so sandy, it was merely corrugated in the past and had sand dumped on it to make it smoother for vehicles. Hmph.)

Riding Through Clouds

by SS at
12:33 pm on Monday 22nd March 10
[dirt, lakeviewcamp, lembo, tanzania]

When we were on school ski trips, our teachers used to always say in our safety briefing that most accidents happen on either the first or last day of a trip because people are overconfident. Certainly this truth seemed to exhibit itself yesterday when on our first day of the second half I was hit by a truck.

The journey out of Arusha was at the peak of the Tanzanian rush hour on a Friday morning. For under ten kilometres we were riding through heavy traffic and riding the wave of adrenalin, I filtered through lines of cars, jeeps, buses and trucks with several other riders. As we approached a junction where a sideroad was joining our road, a truck was emerging slowly. It stopped, edged forwards a bit and then stopped again. Foolishly, assuming the truck had now stopped, I continued forward on our road, with right of way. The truck edged forwards again, pushing me+bike sideways onto the ground. Luckily it didn't advance any further and there was no real damage apart from a couple of bent (possibly fractured) bottle cages.

The driver of the truck came out and apologised profusely. I assume he simply didn't take notice of me. Lesson learnt and I'll yield more often to the African traffic. I took the rest of the day slowly, riding with Erin and Ruben. The paved road was to end at 80 kilometres but the TDA notes must be out of date since we happily rolled all the way to camp (105km) on some variety of pavement.

That afternoon I fixed the remaining issues with my bike, replacing the rear brake cable (oh does it feel good to have full control over the bike again) and redid my handlebar tape which has failed to cover about 20% of my handlebar since our first section of dirt in Sudan. Realising that we would have a significant amount of free time, with the help of some of the other riders, I devised a survey which we're going to ask every rider on the tour. Questions range from useful information for future riders to plain ol' information which is probably not so useful. Keep your eyes peeled for the results.

I slept for nearly 9 hours which seems to have helped my legs regain their speed. Today was a fast day and we hit the dirt road at 4.4km from camp. Thankfully it wasn't as hardcore as the Northern Kenya 'road' and my bike liked it. My body too was relatively happy with the amount of jarring through the handlebars (although I may be swapping gloves tomorrow to prevent a hole being worn into my palms). I started off early and was overtaken about 30km in by Frans (today's stage winner), Simon and Jethro. Just before lunch Gisi and Stuart overtook me.

After lunch, I was overtaken by noone, which was a welcome relief. Maintaining my pace to camp, the only annoyances of the day was the enormous dust clouds that the lorries and buses kicked up as they overtook us. Normally the clouds fade quickly but the sand or dust here is much finer than that we've seen previously. As a result, the air stays a sort of cloudy emulsion for tens of seconds, making it impossible to see (and irritating your eyes) and hard to breath. This is worsened on uneven downhills which require eyesight to navigate safely at any speed.

The second annoyance was being called a 'mzungu', Swahili for white person. I understand that the children here may not be well educated but surely they're able to distinguish between skin colour. (Perhaps mzungu is a general byword for foreigner but I'm a pedant for accuracy.)

The day was quite hilly, involving a fair climb on dirt - this counted as a mando-day, our fouth of the Tour so far. At on point the climb reached a 15% gradient and on that ascent I stood up to try and get enough power to move forwards. I slipped into a sandy rut at this point and my rear wheel lost traction. It wouldn't stop spinning enough for me to roll out of the rut and I had to unclip from my pedals quickly in order to avoid falling.

Looking at the actual ascent, it was under 1200 metres. Supposedly the ascent combined with the dirt made this stage difficult enough to be considered a mando-day. Personally, I don't find there is much difference between ascending on tarmac and on dirt - the speed difference might be a single kmph or so but proportionally this is much less. E.g., on a flat road on tarmac you could be travelling at 30kmph, versus 20kmph on dirt, a 50% speed difference. Climbing a hill, you (or I, because I suck at hills) could be doing 12kmph, versus 10kmph on dirt, a 20% speed difference.

Faith by Limp Bizkit shuffled around as I was grinding up the biggest single climb of 600 metres today, inadvertantly gifting me with a new climbing motto - 'get the f*** up'.

P.S. Happy Belated Birthday to Chirag, sorry for not sending a message sooner!

I hope you're ok from your crash with the truck. Traffic rules are generally respected fully only in developed countries. I live in San Diego close to the US-Mexican border. Just after I cross in to Mex things chnage dramatically. I don't know why. I personally like the survey you are conducting. In epic journey such as this going through different countries and terrain, the question of what to bring is an acute issue for those of us who have yet to do it. I've looked at the current as well as previous blogs. All I see ispost "my bike" or "my equipment".I took a menthal not from your writting on front suspension from earlier journal. I also saw a fairly good description of Rick Wasfy's bike

Rolling Over Muddy Ground

[dirt, kenya, laisamis]

Originally posted on the TDA Blog.

Greetings from your African dirt correspondant, exactly a month on from our first taste of dirt in Sudan. I'm writing from a small settlement called Laisamis, 95 kilometres from a dusty town called Marsabit, en route to Nairobi.

As we left Ethiopia, the heavy rain that had plagued the tour eased up and we were generously treated to several days of dryness. The weather changes quickly though and at 4:30 am on our rest day in Marsabit riders were busily putting their rain flies on their tents. The roads in Marsabit quickly turned to mushy mud and vehicles (including our own bucky, the 'Drama Queen') were getting stuck every few hundred metres. We've not had to ride over any serious mud so far on this tour so this was shaping up to be an interesting riding challenge.

There was no real rain overnight and as the riding week began, we were told of the muddy sections that awaited us on the road. After a pretty serious downhill, I settled down for a morning of gradual descent to lunch. Soon enough the first mud arrived, vehicle tracks were carved half a foot in and any clear cut path soon vanished.

Riding over the mud was slippery and I was very glad of my previously ill-thought out decision to use fairly skinny dirt tyres. The mud attaches to your wheels quickly and within minutes it's rubbing against the inner edges of your frame and fork and collecting on top of your brake callipers, making no sound but slowing you down noticeably.

For one of the early sections, there were a hardened section on the sides of the road which was much quicker to ride along. I was riding along merily at somewhere between 15 and 20 kmph when I caught sight of a local. He shouted and pointed straight across the road to something just metres in front of me. Slamming on my brakes and almost vaulting over my handlebars, the object he was pointing to was immediately apparent - a deep and wide crack in the earth.

Saved from this possible end to my riding day, I continued on to lunch, passing through water logged section after water logged section. The clear rain water turns brown as soon as it touches the soil and the standing water covering the depressed sections of road leaves a layer of fine grit on your skin, clothes and bicycle as you pedal through it. Bicycles were creaking for much of the day as the water washed off lube.

Visible from lunch was another water logged section of road where a truck had got stuck in a seemingly deep pothole. The cab of the truck was arched at 20 degrees to the surface of the water and it seemed that it was submerged about a metre. Normally the puddles aren't that deep, or at the very least, their surface maintains the same consistency as the road immediate before and immediately after it. Another rider Jason was standing on the other side of the puddle scraping his shoes but I took little notice of this. Feeling confident at my ability to ride such puddles, I cycled straight into this puddle, picking a line that followed the ruts on the road leading to it.

The first small puddle was fine but less than two metres into the second puddle I felt my front wheel disappear into some mysterious underwater chasm and I actually went over my handlebars this time. Luckily there was no hard impact, unluckily I was now soaked from neck down. The crew and passengers of the stuck truck broke into laughter and Jason, who hadn't see me cycle in, was shocked to see just my head floating above the water. We stood and watched as three more riders crossed, somehow picking a line where they stayed relatively dry. One of the TDA trucks tried the same and was wedged underwater within seconds.

The afternoon featured the much promised 'extreme corrugation' and arriving to camp was a timely relief. As riders came into camp, it was pleasant to see some of the chronic complainers extoling their enjoyment of the day.

Good to hear from you.Although you may be bruised and tired otherwise you seem to enjoy your ride. Don't forget about the pics. Sorry to hear that this group is probably the last to ride on the lava rocks. I read the Chinese are building a paved road. Ciao.
