Overview
- Organizers said Monday they have more than 10,000 applicants worldwide and will select 128 men, one per country, for races slated in San Francisco next month.
- Chosen entrants will mail semen kits to California for lab prep, and technicians will race isolated sperm on a 400‑micron microfluidic track viewed under high‑powered microscopes.
- The competition begins with individual timing, then seeding by motility into heats and knockouts, and the owner of the first sperm across the finish line wins $100,000.
- Races will stream online with giant screens, leaderboards and posted health data for each competitor, according to plans shared by the event’s founders.
- The same team staged a smaller Los Angeles contest in April 2025 with two college participants, a $10,000 purse and a winning time of one minute and three seconds.
