Hi, Sulis! What is your mileage base now? I know, I know, SLC winters, etc.

The 100 mile American Century states no major climbs and it is highly unlikely that the shorter routes would have any more difficult climbs. Organizers just don't do that. Doesn't look like they're taking you up the Wasatch front but keeping you in the valleys so I think the Challenger is very doable.

Try the Red Riding Hood 30 in June as an intermediate goal and then you'll know. You have 7 weeks to train for a 30 mile ride with no major climbs. You may even decide to go for the Baker's Metric at the ULCER!

Do a little search and you'll find all kinds of training plans by the week for century rides. Some of the links are probably buried in threads on this forum. I find that if I use a training plan (even informal) with progressive goals, I can comfortably ride the distance. The plan should include terrain like the ride.

If you decide to ride the Little Red Riding Hood, give me a holler and maybe we can say hi.

PS - I like your local club rides that say to bring "ice cream money."
