American ultra-trail runner and writer who has quickly risen to the elite ranks of 100-mile racing. Known for his thoughtful race reports on his Substack 'Chasing Trail,' Olson made history in 2025 by winning Western States 100 in his second attempt, holding the lead for over 94 miles and finishing in 14:11:25. A Nike ACG athlete, he combines aggressive front-running tactics with resilience under pressure, demonstrated by his ability to hold off a strong field despite suffering from severe dehydration and stomach issues in the final 30 miles of his Western States victory. Father to Marshall, he balances elite performance with family life.
