I've just learned of a local century ride that is only 2 weeks away. I'd like to join, but not sure if I'm ready. I've been commuting by bike for the last five years. The last year of my commuting has been 18 miles/day that I do at least 4 days/week. Over the last 2 months, I've done several weekend rides of 40-50 miles, but I haven't gone over 50. I usually take one 10-minute break at about the 75% mark during these longer rides. After these longer rides, I'm tired and hungry, but feel like I could keep going at a leisurely pace after eating. Am I ready to leap to 100 miles? I don't have any days between now and the event where I'll be able to go for more than about a 30-mile ride.
The terrain for the century is flat, just like my normal biking.
