As far as I understand, the control points are the same for pairs and individuals, so they both race a comparable length (the precise length will depend on the routing skill of the riders).
However the first man pair at TCR6 (Charles Christiansen and Nico Deportago-Cabrera) finished in
13d 20h 25m, whereas the first man individual (James Hayden) finished in
8d 22h 59m. Riders in pair should have an advantage as they are allowed to draft each other. There is also the advantage of morally supporting each other, which I believe it's very important in such a long race. How come are they slower instead?
The only explanations I can give are: higher probability of mechanical problems for the pairs and less competition in terms of riders that sign up. Or am I missing something else? Do they have more restrictive rules perhaps?
Note: This is being asked for curiousity, but I want to point out that I am a huge fan of Chas and Nico (the winner pair) and I have enormous respect for the spirit with which they approached the race.
Note 2: Here I am only talking about the minimum time of the riders, not average time (I don't have data for that).
Edit I looked into statistics of moving vs stopping time of the above-mentioned riders. Assuming that I am interpreting the tracker stats correctly, here is the info:
moving time 8:15:38 7:05:04
stopping time 5:06:37 1:18:24
This seems to validate @ChrisH's hypotesis in the comments that the biggest difference is in the stopping time.
