Idahoman Xtreme Triathlon is not to be taken lightly. This is a challenging event. It is not your typical ironman-distance triathlon. It is not for the rookie or the ill-prepared. Be honest with yourself. 
Read and memorize the Athlete Guide. Make sure your support crew does the same. It is your responsibility to know everything about the event - inside and out.

Bike (112 miles / 180 km)

Beautiful Fall colors, epic climbs and unpredictable weather greets athletes on this course. The bike heads along the east side of Lake Coeur d'Alene on Hwy 97 to Harrison. From there, athletes climb Hwy 3 to Interstate 90, before heading northeast towards the Montana border and the 13-mile climb up Thompson Pass before dropping into Wallace, Idaho and T2.

Run (27 miles / 44 km)

From Wallace, Idaho, athletes travel west towards Kellogg, Idaho, along the Trail of the Coeur d'Alenes. The first 10 miles (16.2 km) are relatively flat and even slightly downhill. Those meeting the mountain cut-off time wish it would stay that way as athletes face the last 17 miles (27.5 km) along the trails of Silver Mnt ski resort. This route includes climbs up to Kellogg and Wardner Peaks, each over 6200 feet / 1880 m. The race finishes at the Gondola, which athletes and support take down after the finish. Those not meeting the cut-off at mile 10 will continue another 8.5 miles on the Trail of the Coeur d'Alenes to the turn around and double back to the finish at the base of Silver Mnt.

Support Crew

This event is mostly a self-supported event (especially the entire bike and the entire run). What that means is that each athlete is 100% responsible for themselves on the bike and the run. We provide no SAG and no hydration/nutrition stations on the bike. Each athlete must have a support crew (of at least 1) and a vehicle dedicated to hydration/nutrition and mechanics on the bike course. On the run, we provide a couple of hydration/nutrition stations but the remoteness of the course makes it difficult. A support runner is mandatory for the final 16 miles of the run course. Support runners may also run the entire 27 miles with his/her athlete. All support runners must have the same mandatory run gear required of each athlete. Make sure your support crew reads the entire athlete guide. At least one support member must be able to communicate in English with the race organizers.


Do not underestimate the run and your support’s ability to complete the final 16 miles or the full 27 miles because neither athlete or support are allowed to leave each other on the mountain at any time for any reason, without disqualification and being banned for all future years.

Weather & Safety

Expected Water Temperatures and Weather Conditions

  • Water: expect cool water; temperatures can be as low as 62 F (14.5 C) in July.

  • Air: Bike leg - Coeur d'Alene area - lows in the upper 50s, highs can be in the 90s; and Wallace area - highs can be in the low 80s in the afternoon

  • Air: Run leg - Kellogg and Silver Mnt areas - lows in the 50s; highs in the mid 80s.

Potential changes in the course due to severe weather

  • This race takes place in the panhandle of Idaho and the heart of the Pacific Northwest. If the water temperature is colder than 62 F (10.5 C), a full wetsuit will be required. If there are high waves due to wind, the swim course could be shortened or moved to a more protected location. In extreme circumstances, the swim could be canceled.

Severe weather on the bike and/or run legs of the race

  • Weather changes all the time in the Pacific Northwest and expect wind, rain, and mostly likely heat. The end of July has been known to be in the upper 90s or low 100s. 

  • Since the run portion takes place at over 3500 feet elevation (and peaks at over 6000), inclement weather is always possible. The run may be altered if the mountain portion of the run is deemed unsafe by race and local officials.
