The Mantua Reservoir Trail is Exactly 4.1 miles on a Loop - no out and backs just to make the milage. The Loop will make each Yard fly by seamlessly. Picture the headlamps surrounding the lake during the nighttime hours.
Mantua Reservoir in the Springtime - the race is situated on Mantua Reservoir, so there will be no shortage of scenery and wildlife to make your race ultra enjoyable. Springtime in Mantua is highlighted by the famous Mantua Poppy Fields, in addition to the beautifully green farmland and mountain hillsides surrounding the Reservoir.
The Trail is Flat and Fast. My watch registered 20 ft of elevation per loop. The trail is firm dirt with some gravel. Many runners will utilize cushioned road shoes.
