The Thru the Leaves Trail Races are held at Bloomer Park, Rochester Hills, MI on the mountain bike trails. THIS IS NOT A ROAD RACE… all distances are DIRT trails. The trails are HILLY, mostly single track with rocks and roots.

ROUGH DESCRIPTION: First 1/4 mile- thru parking lot to trail, this will help with congestion at beginning. Next 2.75 miles- mostly single track. This is the Hilly, Technical section of the course + 95 stairs! Next 2.5 miles- mostly Flat 🙂 switching back and forth from single track to wide track. Last .5 mile – single track. This will circle you around the finish area, so don’t get too excited too soon.

Half Marathon: 2 loops( 6.6miles each ) Pink = 900 ft elevation gain
10K:1 PINK loop ( 6.2 miles ) = 450 ft elevation gain
5K: Uses most of second half of PINK loop. No stairs. = 225 ft elevation gain

The 6 hour relay on Sunday will take place on a 2.5 mile loop – two or three person teams, must rotate teammates in order.
