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. 2026 ITUS: Click on race name to check out their websites.
