Challenge: to bike every day in April

Just signed up for the 30 Days of Biking!! My ankle is still sore for the 15.5 mile trail run on the 6th. No biking or running since then, I am getting a little antsy. The Shiner 100 mile bike ride is May 7th. A little worried, I want to be able to do the ride. I have to ride this weekend, see how it see. My fingers are crossed.
