Rosaryville 50K is run on single track mountain bike trails in Maryland. It’s a 3 loop course that is fairly flat, not terribly technical (perfect for getting lazy and falling!), and extremely runnable. The Veteran’s Day race was much better weather-wise, with temps in the 40′s and 50′s as opposed to the over 100 degree temps of the July race. With the help of Tom and Hai – Sara and I both ran a 50K personal best time of 5:25. What a fun, fun day to run with friends.
