Most long distance riders tend to be older ... the younger riders tend to prefer to race, they are more focussed on speed than distance. The average age at the 2003 PBP was 49 years old ... and there were riders in their 50s, 60s, and 70s.

Here are some stats for the 2007 PBP: http://www.paris-brest-paris.org/pbp...e=statistiques

And look up information about Ken Bonner ... he rides with the BC Randonneurs.
