Instead, participants will register for and complete various qualifying trail races throughout Idaho, submitting their results to accumulate points. The series itself focuses on tracking your progress and celebrating your cumulative achievements. Expect the individual races you choose to have their own packet pickups and race day logistics, while the series provides the overarching challenge and awards.

It's a community for runners who appreciate the rugged beauty of trails and the satisfaction of pushing physical and mental boundaries. The atmosphere is one of shared ambition and respect for fellow competitors, all while enjoying the stunning Idaho scenery.

Weather snapshot (AI-assisted text)

Given this is a series spanning 'across Idaho' and involving 'various race directors,' weather conditions will vary significantly depending on the specific races you choose and their individual dates. Idaho's climate can range from warm and dry in summer to potentially cold and wet in shoulder seasons, especially in mountainous trail environments. Always check the forecast for each individual race you plan to run.

Terrain & course feel (AI-assisted text)

The series explicitly focuses on 'trail' events, so expect varied off-road terrain. This will likely include dirt paths, rocky sections, roots, and potentially significant elevation changes, typical of challenging ultra and sub-ultra trail races in a mountainous state like Idaho. The description mentions 'amazing views and challenges,' strongly implying demanding and diverse trail conditions.

Points System:

You accumulate points based on the distance and finish time of each race.
How are ITUS points configured?
- We divide the winning time by runner time and then multiply by the applicable points for that race (e.g. 31 for 50k)
- Bonus Points: 1st place -10 points; 2nd place -5 points; 3rd place -3 points. 2nd and 3rd place points are calculated on the formula BEFORE adding the bonus points.
