Course Description

The Free to Run Trail Races are held on a challenging but rewarding 12.5 mile trail loop within Pittsfield State Forest in Pittsfield, Ma. There is approximately 2,500-3,000 ft of gain per loop depending on whose GPS watch you want to trust and some of the climbs are definitely steep. The loop consists of mostly of single track and mountain/dirt roads with a small paved portion. Some portions are fairly technical by most standards. Included in the loop is a beautiful vista at which you will definitely be tempted to stop and take in the view of the Berkshires. 50 Miler runners will complete four full loops. Marathon runners will complete two loops with an additional out and back turnaround at the beginning of the race. Half Marathoners will complete one lap with an out and back as well at the beginning as well.

Note: As with any trail race, the actual distance, elevation gain, etc shown on individual GPS devices will likely vary due to trees, switchbacks, etc. Official times will be based on crossing the finish line for your distance, even if it includes extra mileage on your watch.
