The Tour D'Afrique is officially the world's longest bicycle race (this can be verified in the Guiness Book of World Records) and I'd like to offer some tips to anyone who is thinking of racing it in the years to come. These are based on my experiences and observations of the last 3 months and are based entirely on the current race format. At the beginning of the race there were 35 racers (IIRC) and at the time of writing less than 25 remain.

A brief explanation of how the race works in 2010
The Tour is split up into 96 individual stages (although this is 95 because of the extra rest day we had when the truck broke down) and each stage is raced individually. In addition to individual stages, there are a number of sections comprised of many stages - usually but not always from one capital city to the next. There are separate results for each stage, for each section and for the overall race.

Each day every racer, equipped with a timing button, will clock in and out upon leaving and arriving at camp respectively. Timing is to the nearest minute and stored for each stage. The riders are ranked by time, the winner being the rider with the shortest time. This gives rankings for individual stages, sections and the overall race. If not participating in the entire race, any Tour rider can choose to race particular sections and will appear in results for that section but not the overall race.

The race may not always taken the entire length of a stage and the Tour Race Director may choose to end the race earlier on days where for some reason or another it would be logistically implausible or even dangerous to race - i.e. border crossing days, or entering big cities. Occasionally for similar reasons entire stages are not raced and everyone is given the same time for that stage.

If a racer does not finish a stage for any reason, they are given a 12 hour time for that day. In addition, when calculating the overall results, each racer is given three grace days which cancel out their longest three stage times. Finally, there are several mandatory stages which are particularly difficult or long. These 'mando-days' are not considered when applying grace days. The winner of each mando-day is also given a 30 minute time bonus. In addition, any racer who finishes with EFI status intact is given a 6 hour time bonus.

Racing the Tour differs from merely riding it in many ways which I'll identify below.

1. Take Fewer Photos
Usually you'll need to slow down to take any decent photos, or even stop entirely. That's not generally an option if you're concerned about your time for the day or especially if you're riding with other people (see 3.). The racer's mentality is such that nothing may impede progress.

2. Eat Short Lunches
There is no mechanism for clocking out at lunch - this seems more of a technical failing on part of Tour D'Afrique rather than any deliberate race addition. However long you choose to stop and eat for counts as part of your overall time. This means that on days you are trying to rank well, you won't want to waste time eating. Some racers don't even stop for lunch, others will check in, grab some water and hit the road again. It's not fair but crucial when minutes matter.

3. Work Together
It's necessary and extremely beneficial to ride with other riders. On some stages (hills and dirt) this isn't always possible but on the longer road days it'll be the difference between ranking well and merely surviving the day. You'll save a lot of energy when drafting and in a 120 day long race, you'll hit the wall often - the more you can minimise energy loss, the better.

4. Pick Your Days
It's a long race - illness and exhaustion will probably strike at some point. No racer can race everyday without burning out and the best strategy seems to be to pick the days which you want to rank well. On the other days, it's still necessary to be fast (to maintain your overall standing) but you don't need to work at 90% in order to save an hour and rank high. On some days it's a case of survival - just trying to reach the end of the day.

Jethro, one of the fastest riders here, picks his days - on hilly days, where he is particularly fast, he'll go hard and blitz the competition. In between, he'll ride slower and recover. As for consistency, Rod and Juliana are consistently quick and will be as quick as the fastest racers on some day. They'll ride at a pace that is comfortable for them and as a result can maintain it day in and day out.

5. Choose Your Equipment Wisely
Mechanical failure is something that can be easily avoided by the right choice of equipment and a suitable array of spares. One of the fastest racers here was plauged by punctures because of his insistence of riding on extremely skinny tyres, even on the thorn littered dirt days.

In addition, cater to your strengths. If you're not so great on dirt, pick a bike that will make your job easier. It helps to have interchangeable parts - a Thudbuster seatpost for the dirt sections and a rigid seatpost for the paved sections. If you can, bring a suspension fork - you won't regret it. Most riders are on cyclocross bikes, or at least ride with drop bars - bring inline brake levers which can mount on the top of the bars as well as drop levers. Bring fat tyres for the dirt sections, they'll give you extra confidence which will make you faster.

6. Ride Safely
Crashing will probably end badly, resulting in lost days and 12 hour times or even having to leave the Tour. It's easy when racing to get carried away in the competitive spirit of it all and take unnecessary risks. I was extremely lucky when I crashed not to have to take time off but several other riders have been less fortunate.

7. Leave Late
A favourite tactic of racers is to leave (as a group) late from camp in the morning. In a group, it's easier to set a faster pace and catch slower racers - once you've caught someone who you left after, you've effectively beat them for the day. If you leave early and are able to maintain a fast enough pace, you won't get caught but there's a very real danger that you will get caught.

8. Don't Get Ill
This is easier said than done but illness will drag your race time up and make it much harder to finish the stage. Stomach issues may destroy your appetite and not being able to eat enough is a recipe for disaster. Likewise, having to stop regularly because of diarhoea will make it harder to be competitive. Nearly all of the racers have been ill at one time or another.

Given the option, I'd probably choose not to race the Tour if signing up again. While the race has been fun and if I finish, I can say that I've raced the longest bicycle race in the world, I'm not competitive enough of a racer to make it fully worth the sacrifice. I'm going to try and take more photos over the remaining five weeks while trying to maintain my number 10 rank. That said, racing, as well as EFI, is a great motivation on the harder stages.

If you think you can win the race, or even win a section, sign up to race. If you're more concerned with experiencing the African continent then stay as an expedition rider and perhaps race individual sections - it doesn't mean you have to cycle slower, just that you're not always in such a rush.
