Decided to set a goal that means something, and raise some funds for a good cause in the process, so I registered for the Tour de Cure in March here in Florida. I'm going to try for the 50 mile route (I know I won't be ready for the 70 or 100 miles by then).
Should be an interesting journey towards being able to do 50.
Plenty of time to get the distance up. I've done 20 already, so 50 in 20 weeks is more than possible.
