Intro: Seth James DeMoor’s “Most Difficult Long Run Course | 2K | Running Gear Haul” features one of his toughest long runs. The key takeaways are below so you can try it today. Watch the full video for gear and technique.

Key points:

• A 2-mile loop around Boulder with roughly 2,000 feet of climbing. One of Seth’s toughest long-run options.
• His run totaled 23 miles at an average of 7:26-7:27 min/mile. The final 8 miles got rough due to dehydration.
• He highlights recovery gear (compression sleeves, wool socks) and stresses carrying enough water on long mountain courses.
• Treat the loop as race-day practice: steady effort, handle climbs well, plan food and drink in advance.

Workout example:

Goal: 23-mile long run on the 2-mile loop (about 2,000 ft gain)
Pace: about 7:30 min/mi steady (adjust to your marathon pace)
Structure:
- Warm-up: 1-2 mi easy jog
- Main set: 10-12 laps of the 2-mile loop (about 20-24 mi total)
  - Keep effort consistent on climbs (shorter, quicker strides)
  - Recover on descents but stay moving
- Hydration: carry at least 1.5-2 L of fluid (hand-held bottle plus small pack), drink every 15-20 min.
- Nutrition: 30-45 g carbs per hour (gels, chews, or fruit).
- Cool-down: 1-2 mi easy jog plus stretch.

Adjust total distance or pace to where you are in training.

Closing note: try this tough course, modify distances and speeds to your program, and log it in the Pacing app. Drink plenty of water.
