I wrote quite a bit last year about Endomondo’s National Bike Challenge. This year’s challenge begins May 1 and they upped the ante. Last year we wanted to hit 50,000 cyclists riding 10 million miles in four months. The result was 30+ thousand riders smashing to bits that 10 million mile marker. This year’s goal is 50,000 cyclists and 20 million miles in 5 months! We’re going to need the cyclists to make this one happen! Head on over and register. It’s really easy. Then all you do is track and log your miles. There are some really sweet prizes to be won as well. What are you waiting for?
