The graphs above show the number of people who finished the Transcontinental Race (TCR) before (light green) and after (dark green) the finish party, which is at the end of the 15th day, and the number of people who scratched / did not finish (DNF, orange). You can click on an image to enlarge it.

The first graph displays the *absolute* numbers of people in each category; the increasing height of the bars shows how the number of starting places has grown each year. The second graph shows the *relative* number of people in each category; the decreasing height of the green bars over the first three editions shows how the level of difficulty generally increased, but it then reverted to a more intermediate level in the fourth edition.

Looking in more detail at what happened to specific categories of people provides the following insights:

- 412 different people have started at least one edition, only 24 of whom are females.
- Mikko Mäkipää is the only person to finish (or even start) all 4 editions.
- Six people have started three editions, only one of whom has finished all three: Kristof Allegaert (who won all of those 3), the other five people have finished two of the three: Josh Ibbett, Matthijs Ligt, Martin McConnell, Mike Sheldrake, and Chris White (myself).
- 74 people have started two editions, only 24 (32%) of whom finished both, 35 (47%) finished 1 out of 2, and 15 (20%) finished neither edition.
- The only female to have finished two editions is Jayne Wadsworth.
- The probability that someone will finish their rookie edition is 62%, but this probability remains about the same for race veterans when trying to complete their second edition.
- 81 of the 254 people (32%) who started the TCR in 2013, 2014, or 2015 as a rookie returned as a veteran at least once.

# Drop-out / Scratch Rate

In the 2016 race, very few people dropped out before reaching the first checkpoint and almost everyone who made it to last checkpoint made it to the finish. This pattern is shown by the green line in the graph below being slightly *S*-shaped, which suggests that the likelihood of someone scratching from the race may not be constant throughout the race.

To understand this graph, start by looking at the data points on the far left, which correspond to the start of the race, or 0% of the route completed. These are the simple probabilities that someone will finish the race given that they started. For example, 2014 is shown in red in which 64 of 87 starters were able to finish, so the value is 74%.

The intermediate values are more complicated: for example, the fourth of the six data points on the green line corresponds to Checkpoint 3 in TCR 2016, which was the Passo Giau in Italy at about 42% of the way into the race (about 1600 km ridden out of 3800 km); 158 people reached that checkpoint, of which 138 ended up finishing the race, so the value marked is the “conditional probability” of 87%. How many starters there were or how many dropped out before a checkpoint doesn’t affect the value for that checkpoint (but the values of some previous checkpoints are obviously affected by those things).

The overall average results from all editions of the race are shown by the black line. The straightness of the black line suggests that the drop-out / scratch rate is quite consistent throughout the race with approximately 1% of riders scratching for every 100 km ridden. This rate doesn’t really go up or down much during any specific part of the race when looking at the overall instead of just the 2016 results. Therefore, if two checkpoints are 800 km apart then it should be expected that an additional 8% of starters will scratch somewhere between them, regardless of where those checkpoints are on the race route.

# Finish Times

How long it took people to complete each edition of the TCR is shown in the next graph. Medians and percentiles are shown because the distributions are skewed / asymmetric. The median (the central line in each box) shows the time that 50% of finishers arrived before and 50% of finishers arrived after. Four other percentiles are shown to give an idea of the degree of variation. The winning time and the time when the finish party ended are also shown.

2015 had the slowest winning and average finishing times, but this was mainly due to the route being longer than for the other editions. The final figure below therefore shows the distances ridden per day.

# Distance Cycled per Day

The finish times were combined with a rough estimate for the distance ridden in each edition of the race (3300, 3600, 4200, and 3800 km, for 2013-16, respectively) to obtain the estimated distance cycled per day. The format of the following graph is similar to that for the finish times above, except that in this graph higher values are strived for instead of lower values.

The slightly lower distance ridden per day in 2016 (median = 258 km per day) than in 2014 and 2015 (median = 267 km per day for both) shows the effect of the more mountainous route. The data from 2013 is not very reliable because there were so few racers (the 20 finishers rode a median of 252 km per day). 2016 has the largest amount of variation between individuals, which may reflect the fact that the race has become popular among cyclists with a wider range of abilities.

The 2016 and 2017 routes were designed so that someone who averages about 250 km per day should finish in time for the party and this graph shows that the average finisher has always slightly exceeded this rate of progress. Someone who wants to be in the top 25% of finishers probably needs to average at least 300 km per day. Someone who rides more than 350 km per day should finish in the top 5%. Someone who only averages around 200 km per day not only won’t make the party, but also won’t see very many other people on the road after the first few days.

The estimated distance per day for non-finishers is shown on the right-hand side of the graph above. This is based on the times that those people reached the final checkpoint before scratching and the estimated distances to those checkpoints. This data only includes people who reached at least the second checkpoint because speeds to the first checkpoint are much higher than in the rest of the race due to riders being fresh and taking less sleep breaks until that point. The data from all editions is shown together to make the summary statistics more reliable (data is available for 129 people). It’s apparent that a broad spectrum of people scratch from the race, including some people who were on pace to finish in the top 5% before scratching but also many who were doing fewer kms per day than the average finishers.
