Intro

Seth James DeMoor’s The DRONE RUNS with You! covers an altitude training approach. Here’s what we took away and how to adapt it for your own running. Watch the full video for Seth’s complete methodology.

Key points

• Training above Denver’s altitude builds aerobic capacity. Seth covers this in a recent Q&A, explaining how thinner air works to your advantage.
• The session combines distance work and hill training on the same day, showing how to structure back-to-back workouts.
• Content creation alongside training: Seth filmed the entire session with a Skydio 2 drone, showing that you can gather footage while putting in quality training.

Workout example

Morning long run:

• Distance: 15 miles.
• Pace: 8:15 min/mile (steady, controlled intensity for altitude work).

Afternoon hill session:

• Distance: 3 miles.
• Structure: warm-up plus uphill pickups (repeated surges up a steep gradient) for around 25 minutes. Hill repeats build muscular strength and power. Pace varies by individual. Run hard on climbs and recover on flatter sections. For more on interval design and periodization, see Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them.
• Optional: place a drone on a tripod and run a roughly 800 m loop repeatedly for time-lapse capture.

Practical tips

• Request a late morning checkout (10 am or later) to get more sleep before the long run.
• At altitude, keep paces easier and let the environment do the conditioning work.
• Pair training with filming: position a camera or drone, run short repeated routes, and collect footage during the session.

Closing note

Try this altitude-based two-session format. The framework adapts across goals. Whether you’re working on Mastering 5K Speed: Proven Interval Strategies to Cut Minutes off Your Time or building volume for a longer race via Mastering the 10K: Proven Training Plans, Pace Strategies, and How a Smart App Can Elevate Your Performance, strength-focused hill work helps. Scale distances and paces to your current fitness in the Pacing app.
