About the Event

TEST YOURSELF

This isn't your ordinary Ultra - this is a DENFIT Ultra.

DENFIT will make its Buffalo debut at Buffalo Ski Center in Colden, NY. 

The race will BEGIN AT MIDNIGHT with both 50k and 100k runners having the same start time. The course will be a 10k loop up and down the ski slopes. 

The course will NOT be lit; there will be reflective flagging and lawn flags marking out the course as runners make their way through the dark.

100k runners will have 18 hours to complete the course, which will be 10 laps.
50k runners will have 10 hours to complete 5 laps. 

At the base of the ski hills will be a large tent with food, bathrooms and a place for gear so runners will be able to grab what they need before heading back out on course. Headlamps are mandatory, naturally and runners will be required to have them until 7am. 
(tbd if runners are allowed to bring their own tents, but there will be multiple tents at basecamp for runners to use)

Expect the finisher medals to be no less than 7inches in size.
However - ONLY TOP TEN male and female for both the 100k and 50k will receive a custom, special edition spear. 

Top 3 male and female in both events will receive additional prizes and awards.

 

This will not be easy.

There will be elevation. Much elevation.

Expect surprises - there may be natural obstacles along the way, whether it's ducking low branches or scrambling over fallen trees.

Per the GM of the venue, there may even still be snow at the top of the hills.

Prepare.
