Intro

This is a quick summary of We Ran An Ultra Marathon In The New Nike Ultrafly from The Running Channel. It’s a great watch — we’re breaking it down so you can try the workout today. Be sure to check out the full video for all the details.

Key Points

The run is a 6‑hour ultra challenge on the Selfie Forest “Big Bear” course – laps are 3.5 mi (≈5.6 km) each.
Goal: complete as many laps as possible (the current record is 10 laps). The host targets 10 laps (~35 mi / 56 km).
Pacing strategy: stay around 5:15‑5:30 min/km (≈8:30‑9:00 min/mi). Start a bit faster, then settle into a comfortable rhythm.
Practical race‑day tips: use compression socks to limit swelling, stay hydrated, eat on the move, and keep music for mental boost.
Shoe insights: the Nike Ultrafly’s carbon‑plate, ZoomX foam, and Vibram‑style lugs give a good blend of spring and grip on soft, muddy trail; size down a half‑size for a snug fit.
