Whew! Sounds like a great time...I'll have to keep that goal in mind (1 mile for every year) as I am homing in on 50 in a year or two and that would be fun. As it is, last month I rode 21 miles on the 21st for my birthday...
Wish we had a nice area or park to ride in here, we do have a MUP but it isnt very long and it gets a little boring doing short laps on it.
Best Birthday wishes for a happy riding year ahead!
