Packet Pickup Location TBD, Friday August 23rd, from 11:00pm to 6:00pm.  If we are not sold out, last-chance registration will be at packet pickup Aug 23rd.  Packets will also be available race morning but things may be hectic.

1. Everyone should carry a personal hydration device.
2. Everyone must start with the pack at the official, advertised start time.  Pre-running will not be counted as an official result.
3. If you impede another runner's progress or endanger them via tripping hazard or contact, you may be subject to disqualification.
4. Dogs:  One dog per runner, please.  Dogs must be on a leash at all times.  Additionally, the dog counts as an extension of you as a person, and rule #3 will apply in extension.  Running long distances may be dangerous for your animals - be smart.
5. The race is sanctioned by the USATF and will be run in accordance with their rules in addition to our own.
6. Other rules may be provided by the race directors prior to the start of the race.  In certain situations, failure to follow rules may result in disqualification.

UTMB Qualifying RaceUMTB Qualification:  The 100k is a UTMB approved qualifying race worth 3 points.  For official details please visit

Aid Stations:  Aid stations will be located at the intersection of FR-N4130 with Tyler's Traverse, and at FR-N4110 with Lower Storm King.  A third aid station will be located at the start/finish area at Wanoga Snow Park. 

The Course:  See the interactive course map at the bottom of the page.  The 100k is shown; a 10k opening loop to the west then three laps of the larger 30k loop to the east.  The 30k will be one lap of the large loop.  The 100k and 30k events are sanctioned by the USATF for 2019.

Cutoff times: for the 100k will be midnight (18 hours). There will be a mid-race cutoff at Wanoga at 24.7 and 43.5 miles based on projected finish pace (approx 17:00/mi pace) at 1:00pm and 6:20pm.

Volunteers will be needed for the aid stations.  We will have AM and PM shifts.  So you'll have flexible time/locations you can sign up for if you or a friend/relative are interested.  Details will be posted as soon as we set up the tasks (probably in late spring).

USATF Sanctioned Event

I was a 2:27 marathoner that seemed to have hit the ceiling. It seemed that I couldn't break that time. I ran a 2:20 marathon this past fall and a big reason for that success was due to coaching and guidance. Coaching is like having a second set of eyes on a problem.

As an active duty service member we are taught "Attention to Detail." I was focusing on my stronger attributes while neglecting my weaker ones. My personal coach pointed a few things out and changed a few of my workouts and like magic; I smashed my PR in the marathon.
