Grand Valley Marathon ~ Saturday, May 6, 2017
“If you like small town races with minimal hassle that are well organized with a scenic course this is the one for you. The course has a few small rolling hills but very minor compared to most races in CO. There are amazing views of mesas and the CO river. The course winds through CO wine country. I ran on the shoulder of the road and ocassionaly on the white line. I recommend running in your roads shoes without any supplies as the aid stations are well stocked and numerous (every 2 miles).”
