Intro

Running up a 14,000 foot Mountain (1) from Seth James DeMoor is worth watching—and worth trying. We’ve extracted the key elements so you can attempt the workout yourself. Grab the full video if you want more detail and context.

Key Points

• Altitude training at a 14,000‑ft Colorado “fourteener” is Seth’s way of building aerobic power and pace.
• The typical ascent is about 6 mi up with ~4,000 ft of climbing (12 mi total out and back).
• Seth uses mountain runs as a specific endurance workout that translates to better half‑marathon splits.
• Footwear is important: shoes with solid traction work best on ice and snow (Salomon Gator, Speedcross). Layer up for cold, damp conditions.
• Track your summit times and aim to shave off minutes each run — Seth’s best is 1:17, his recent outing was 1:33.

Workout Example

Mountain Altitude Run – 6 mi Up, 6 mi Down (≈4,000 ft gain)

1️⃣ Warm‑up: 10‑15 min easy jog on flat terrain.
2️⃣ Ascent: Run the 6 mi uphill at a steady pace, working at about 75‑80% of your max HR. Focus on holding a consistent effort rather than chasing speed; snow and ice will slow you naturally.
3️⃣ Reach the summit.
4️⃣ Descent: 6 mi down at an easy effort (60‑65% HR). Keep your footing secure on slippery terrain.
5️⃣ Cool‑down: 10‑15 min easy jog or walk.

Goal: Once acclimated, try to summit in **1:15–1:20**. Adjust your target based on conditions and fitness level.

Tip: Use the Pacing app to record your mountain runs and track how your pace and effort stack up over time.

Closing Note

Try this altitude work on a steep hill or mountain—it builds serious strength and endurance, plus mental toughness. Customize the distance and pace for your fitness, log it in the Pacing app, and see what you learn. Check out Seth’s full video for more ideas and motivation!
