Intro

Ryan Clayton’s 8 HRS IN BROWN COUNTY GROUP RUN // The Road to Steamboat Springs #19 is worth your time. Here’s the breakdown of what makes this workout tick. Try it yourself today. For the full picture, watch the video.

Key points

• An 8-hour ultra completed on an 8-mile loop (≈12.8 km) in Brown County, Indiana.
• Target was 4 loops (≈32 mi/ 51 km). The runner finished 3 loops (≈24 mi/ 38 km) in roughly 6 h 24 m.
• Heat and humidity were serious factors, with temperatures reaching 95 °F/ 35 °C.
• Fueling kept things straightforward: pacing with wind assistance and a spoonful of nut butter grabbed at aid stations.
• Tip: Keep water bottles within reach, refill at the halfway aid station, and test fresh shoes with a short run before committing to a full loop.

Workout example

Run 8-mile (12.8 km) loop at a comfortable effort (~13-14 min/mi). 
Repeat 3-4 times within an 8-hour window. 
During each loop:
  • Grab water at the halfway aid station (≈4 mi/ 6.5 km).
  • Take a quick nut-butter bite for a fast-acting calorie boost.
  • Monitor heart rate and stay in the "easy-to-hold-on-to" zone despite heat.

Closing note

Give the 8-mile loop a shot with your own training. Adjust the number of laps and your pace based on your current fitness, log it in the Pacing app, and refine the workout to match your goals.
