3 things that worked
Stove: If the race was not challenging enough, Jay Petervary and crew wanted to see if you knew how to use your gear. Whether it was announced or not, there would be a mandatory stop where you had to boil water with the stove you carry. This was a great idea as it made me figure out what gasses worked well in cold weather. I purchased an MSR Whisperlite Universal, because I do plan on using it down the road, and I already owned a JetBoil Sol. My intent was to use the Whisperlite Universal for white gas and the Jet Boil for isobutane. Isobutane tends to have a difficult time in really cold conditions, while white gas does not. About a week before the race, I put my isobutane canister outside in around 5 degree weather. About 3 hours later I went for a ride to test it out.


3 things that did NOT work
Tires and PSI: We arrived up in Island Park on Thursday night around 7pm. Every available second after that I was checking my psi to make sure my tires were holding air. The Tuesday before the race was the first time I setup my new Nextie Wild Dragon 90mm tubeless rims, and I was extremely nervous about it. I was having crazy pressure variations as I would bring the bike in from the cold, and back outside, 5 psi one minute, 13 the other. Luckily for me the psi would not be the issue during the race, but rather my tire selection. I ran a Husker DU rear and a Dillinger front, both of the 4 inch variety. I was riding these tires a few weeks prior to the race and they were working extremely well. Temperatures were cold in Colorado, and that is where I was fooled.


There is always room for improvement in these things and athletes will continue to stretch the limits of gear. Like I said, I think it’s better to play it safe, especially if you are in some nasty conditions. All it takes is a broken bike or huge storm that leaves you stranded in the cold. Yes, I am still new to winter ultras, but I hope some of this information can help your next adventure or race. I’m hoping for a longer, multi-day race in the lower 48, I think this setup would work perfectly for that.
