I don't know just what the name is all about but the race...it's a lot of fun. It's 25K at Murphy-Hanrehan park in Dakota County. (A half-marathon is 21K for comparison.) Here's the link http://surfthemurph.org/
There are 25K, 50K and 50mile options on the day. The 25K starts at 8AM...the sun will rise after the race starts, making the first few miles gorgeous. Picture a stream of runners wearing headlamps and the light reflecting off trim on shoes and jackets. It gets warmer. There might be bits of snow. It's delightful.
The trail...the first and last few miles are hilly. Not insanely so but you will notice the hills. There are some stretches of single track in the hilly sections. The flat section is wide open. The aid stations are first-rate. All in all, it's a fun fun day!
Think about it!
