Remarkably I topped 600 for month today. It was surprising considering the short month and you never can predict how many riding days you will get. Our forecast is sketchy for the next few days, but with some luck maybe I can get 700.
If you are doing the 300 mile challenge on MapMyride they have made a change. When you reach 300 miles they close the challenge and you can sign up again starting the next day. I completed the challenge twice for the month.
Good luck to everyone else and keep pedaling for the 500!
