Hello, I am new to road cycling, I got into it about 2 months ago. There is a 75 mile ride at the end of November, but I don't know if I would be able train enough to do it. I don't want to bite of way more than I can chew. I ride about 5 days a week, each ride is between 10 and 25 miles. My longest ride to date was 31 miles with about 1000ft elevation. Where I am now, I beleive I can keep a good pase for about 45 miles. Is 70 days enough time to train or should I sign up for the 42 mile ride they have the same day? Sorry if you saw this posted in the general topics also. I wasn't sure where the best place to post it would be.
