A group of about 50 brave souls started the 24-hour America's Mountain Adventure Race Friday evening in Green Mountain Falls. The racers will travel through the night by foot and bike, with the route taking them nearly to Cripple Creek and back, They stop at check points along the way as proof that they completed the route.
The fastest racers should complete the distance in about 18 hours, but many will take a full day or more.
There will be shorter adventure races beginning on Saturday. All will finish at the lake at Green Mountain Falls.
