Yes. Entry to the 100K is gated and you need to meet one of four published standards before race day. They are a previous Jawadhu Hills Ultra finish, two sub 5:30 road marathons in 2026, a 50K or longer trail finish inside the official cut-off in 2026, or a 75K stadium run in 2026.
A finish at the 60K in the 2024 edition or the 50K in the 2025 edition is accepted. You will be asked to share the official results link as evidence.
Every qualification route asks for proof. That means an official results link, an official result with timing, or a recorded activity depending on which standard you are using. Gather these before you start the entry so the review can move quickly.
No. Participation in the 100K is listed as solo, so each runner covers the full course alone.
