Yes, you’ll get muddy, yes there is running, yes there are 11-14 obstacles but NO fire, NO barbed wire and NO electric shocks! The 3.5 mile course starts at the top of the mountain at Spruce Lake (they will even give you a ride up on a chairlift) and runs along the ridgeline then down the hill. The 5.4 mile course adds a bit of uphill running, just in case you’re feeling especially tough.
