I checked out the Clear Creek trail yesterday. If we start at the Church Lane entrance and run to Tapp Road the distance is approximately 2.5 miles. There are signs on the Clear Creek delineating each quarter mile. I propose two laps ~ 10 miles plus a shorter last loop turning around at the 1.5-mile sign. For the people doing the quarter marathon, I would suggest one lap ~ 5 miles plus a shorter last loop turning around at the 1.25-mile sign. Thoughts?
