Sehgahunda Trail Marathon & Relay

Update as of April 1st, 2021:

The following email was just sent to all 2020 Registrants to remind you to exercise your options.  We have extended the date to complete this task to April 7th.  After that you will be deferred to 2022.  Here is the letter sent via Run Sign Up and from Ellen Brenner's email - CLICK HERE

Update as of March 26th, 2021:

Update on Day 1 Busses: We are able to acquire busses BUT here is the situation in order to have them. Busses can only be at half capacity currently which equals 22 people/bus and only one person/seat. No seat sharing. Which actually is pretty sweet, but I digress. In the next week or so, once day 1 registratio/transfers end, we plan on opening the opportunity to buy a seat on the bus for $10. It is for Day 1 participants only. Masks must be worn the entire time on the bus. The bus will take you from Parade Grounds to the start at Mt Morris. There will be specific time slots that you will be buying. Stay tuned for when that opportunity opens. Thx Ellen

"Dare to Experience" Sehgahunda!
Pronounced (Say-ga-hunda)


The Sehgahunda Valley (“Vale of Three Falls”), which encompasses the portion of the Genesee River Valley, was comprised of several villages settled by the Seneca People. The locations of these villages make up the current boundaries of Letchworth State Park.
Letchworth State Park spans over 14,000 acres, with miles and miles of trails - all with varying degrees of technicality to challenge both experienced runners and casual hikers. Many of the trails that make up this race are the very trails used by the Seneca Indians to access the Genesee River, which bisects this valley, giving rise to its nickname “The Grand Canyon of the East.”
We dare you to experience the beauty, history, and challenge of this unique event!


  • Chip Timing by YellowJacket Racing including Net Time (The time from when the gun goes off until you cross the start line is subtracted from your official gun time to get your net time)  Note: As per USATF Rule 163 we do not use net times for awards, they are provided by us to you as an additional service only.
  • 7-8 aid stations along the 26.3 mile course providing pre-packaged food and water.
  • Post Race Grab n Go Bag of food and drinks, along with medal

  • Most trails heading out to the check points are marked with blue blazes
  • All turns from the main trail onto the check point trails and from the check point trails back onto the main trail will be marked with arrows and small flags

A MapMyRun course map can be found here.
Note: this is not an official map, just one taken from a GPS watch which can be inaccurate over the long distances, sharp turns, and steep inclines.


The Parade Grounds entrance to the park is off at Portageville Road in Hunt, NY. GOOGLE MAP for directions. We are working on day of packet pickup (if it exists) and bussing to ensure proper protocols.
