Intro: Seth James DeMoor’s Run Longer, Improve Endurance, my 10-Year Reflection has solid insights. Here’s what you need to know to try the workout today. The full video is worth watching for the context and reasoning behind these principles.

Key points:

• Aerobic engine: running consistently strengthens your heart and improves oxygen circulation, which makes race-pace efforts easier and speed work more enjoyable.
• Consistency and recovery: hold steady weekly mileage, keep gaps between long runs to 7 to 10 days, and stay on top of injury prevention through prehab, good shoes, and softer running surfaces.
• Annual volume: build your annual mileage gradually. Aim for 500 to 700 miles per year as a foundation, or 1,000 to 1,300 miles if you’re further along. Add hill repeats or vertical work to build leg strength.
• Steezy run: a “steady-easy” effort around 8-minute mile pace (7:45 to 8:15 per mile). Fast enough to push your aerobic capacity without crossing into uncomfortable territory.

Workout example, the steezy run:

1. Warm up with a 5 to 10 minute easy jog.
2. Hold a steady 8-minute mile pace (7:45 to 8:15 per mile) for 30 to 45 minutes.
3. Cool down with 5 to 10 minutes at an easy pace.

Adjust the time to match your current fitness level. The goal is to find that “steezy” zone, fast enough to stress your aerobic system but controlled enough to finish feeling strong.

Practical tips to try right now:

• Block out weekly runs and avoid letting more than 7 to 10 days pass between your longest efforts.
• Once a week, add a short hill repeat (30 to 60 seconds up a gentle grade) to add vertical gain and build strength.
• Track your annual mileage in the Pacing app and target a 5 to 10% increase year over year.

Closing note: try the steezy run today and scale the pace and length to your current fitness. The Pacing app lets you customise the workout to match your goal paces and targets. Stick with this rhythm, and those longer, harder runs will feel noticeably easier over time.
