20th Annual Cotswold Bike Ride
52.5 weeks of 2010 [Week 19] Not a great photo, but wanted one to capture this for my week. I did the 40 hilly miles (~65km) of this ride in 2 hours 46 mins (or 3 hours 10 including stops!). I've done it seven times in the last 10 years (not sure how many in the 20 years).
