Mendon Trail Run 20k is part of the Trail Runner of the Year Series

Thanks to everyone for participating this year! See you next year

Course Description

10 km loop course entirely on trails. The course will be marked, turns marked at trail junctions, and traffic cones at the road crossing. The course has several rolling hills. All of the hills are run-able, but there is one short, steep climb halfway through the loop that many participants choose to walk. Estimated 1000 feet of climb per 10k loop. There will be two crossings of park roads per loop. Runners are responsible for their own safety when crossing roads.

Event Information

Location: Stewart Lodge, Mendon Ponds Park
Bib number pickup: Friday November 2 from 5:00 to 8:00 PM, at MedVed, 3400 Monroe Ave, Rochester, NY. At race for 50K, from 7:00 to 8:00 AM. For all other distances, from 8:05 to 9:30 AM.
Awards: Overall M & F, plus age group (10 year) winners in each race. Race souvenir to all 50K finishers.

Aid station for 20K, 30K and 50K runners at start/finish, plus one water stop about 3.5 miles into loop.
Pacers will be permitted in the 50K only, and only for the last two loops. There is no charge for pacers, but we require that you fill out a waiver. See the registration table for the waiver. There are several rules for pacers, most of which are common in ultras:

  • Pacers can't carry supplies for the runner (they can't carry the runner's Camelbak if they have one, for example; they can't carry their water bottle, or food for them, etc.)
  • Since we won't be charging for pacers, pacers are not allowed to take supplies for himself/herself at the aid stations.
  • The pacer can't run through the finish line with the runner, either at the end of the race or when finishing a lap.
  • The pacer must arrive at the aid station with the runner or after the runner, and must leave the aid station with the runner or before the runner. So the pacer can't race ahead and be filling the runner's water bottle, rounding up food items, etc., or linger after the runner has left the aid station.
Tee Shirts: Tshirts are available for order. The fee is $15 per shirt and is in addition to the registration fees. Tshirts may be ordered online during registration and will be available at Bib pickup. Shirts will be long sleeve,100% polyester with a Jersey feel.

Refunds: Full refund minus $5 administration fee up to October 5. No refunds after that date.
