I did 23 centuries in 2005 just to say "I did it". But that was all for the fun of it!
Gina and I have done 4 centuries on our tandem so 3 months ago I talked her into a flat century on her single just to say "she did it". Overall it was fun but this ride was a more of a to say "she did it".
101 miles @15.8 average and she was smiling at the end of the ride....and yes, Gina is 50.
