About this app

The official-data companion app for the Western States 100-Mile Endurance Run — the world's oldest 100-mile trail race, run every June from Olympic Valley to Auburn, California.

Race day, you're seconds behind every runner you care about. Off-season, fifty years of finishers, splits, and stories are at your fingertips.

Race Day

• Filter by gender, age group, US state, country, or aid station
• Course-record badges — instantly spot runners on or under CR, CR-F, AGR, and AGR-F pace
• Leader gap badges — see how far behind 2nd–5th overall, women's, masters, and age-group leaders are running
• Tap any badge to head-to-head compare splits with the runner setting the mark
• Persistent live video player — watch the broadcast while you scroll, switch tabs, or open another runner's page
• Push notifications when runners you've favorited reach a new aid station, finish, or DNF
