Intro

Seth James DeMoor shares a birthday‑mile challenge in “Sub-5 Mile at age 40? My FUN Birthday Challenge as a Master’s Runner”. Great content — here’s how to use the birthday‑mile workout yourself. Check out his full video for all the background.

Key Points

• Birthday Mile: race a single mile around your birthday, aiming for a birthday‑mile PR instead of chasing a lifetime best.
• Goal: sub‑4:38 mile at age 40 on a track, with race‑intensity effort.
• Quarterly Tradition: schedule a birthday‑mile each quarter (July, August, September) to maintain consistent speed training.
• Training Approach: cut weekly mileage back to 80‑100 miles while emphasizing track workouts (200 m, 400 m, 800 m repeats) to develop the speed needed for mile pace.
• Pacing Insight: running a quick mile requires being fast at the shorter distances first—build from 200 m through 800 m repeats to prepare.

Workout Example

1. Warm‑up – light jogging, dynamic stretches, and switch into your spikes.
2. Mile Time Trial
   • Target sub‑4:38 (around 68‑69 sec per 400 m). Shoot for 68 sec on your first 400 m lap, bump to 70‑71 sec on the second, and maintain that pace into the third.
   • Run on a track or similar flat course and capture each 400 m split.
3. Post‑run – reward yourself with cake, then record the result in your Pacing app and calibrate your paces going forward.

Practical Tips

• Mark the birthday mile on your calendar and training log so the quarterly check-in doesn’t slip through the cracks.
• Maintain weekly mileage around 80‑100 miles to give speed sessions the attention they deserve.
• Progress through interval distances (200 m to 400 m to 800 m) to develop the speed foundation a fast mile demands.
• Lean on the Pacing app to set your split targets and dial in your own rhythm.

Closing Note

Try the birthday‑mile this month—adjust the splits to fit where you are now and save the results in your Pacing app. You’ll gain real progress, enjoy the process, and stay fast in the years ahead. Enjoy the run!
