Need an off-season goal? Go long (really long).

You have the fitness. You have the motivation. What you don’t have: a race. In North America, triathlon seemingly goes into hibernation from Thanksgiving to St. Patrick’s Day, with few opportunities for swim-bike-run. Though some triathletes welcome a relaxing off-season to rest and rejuvenate, others are chomping at the bit for big miles and even bigger goals. It’s no surprise, then, that triathletes naturally gravitate toward ultrarunning. The physical and mental fortitude an athlete builds while training for a half or full Ironman also translates nicely to the challenge of running 50K, 50 miles, or even 100 miles.

The best part? Unlike triathlon, ultrarunning is a year-round sport, with plenty of opportunities to race in the winter months. Get ready to log some serious miles at one of these beginner-friendly winter ultrarunning events.

Everything is bigger in Texas, and this ultra race is no exception. Unlike many other ultramarathons, which take place in remote locations on dirt trails, the Urban Ultra is a nighttime 50K of paved trails under lit-up Houston skyscrapers.

Each runner is free to walk and stop (to eat, sleep, blow a few party horns at midnight) as they wish, though the clock will keep counting down.

Hilo to Volcano 50K
Moku Ola, Hilo

The ultimate Hawaii souvenir? An epic race story. You’ll get it at the Hilo to Volcano 50K, a challenging-but-awesome ultra that begins at sea level in Hilo and ends in the big island rainforest just outside of Hawaii Volcanoes National Park.

Moab, UT
January 26
Madmooseevents.com

Winter is a perfect time to run in the dry desert of southern Utah. At the Arches Ultra, Moab’s newest trail race, runners can take on a 50K or 50-mile route along the border of Arches National park.

Florida Skydive Ultra Run
Clewiston, FL
January 24-27
skydiveultra.com

Though most of the course at the Skydive Ultra is flat, the first two miles have a lot of elevation change – 13,500 feet, to be exact. The race is exactly as its name implies, with athletes starting their 50K, 100K, or 200-mile race by jumping out of a plane. (If you’re partial to solid ground, there is an option to forego the jump and run the first two miles instead.)
