Office Hours: 300m Repeats

  • Jones Track 2301 South Federal Street Chicago, IL, 60616 United States (map)

Office Hours is Inner Lane's weekly track session. It is geared towards our athletes but open to everyone.

Inner Lane coaches provide the workout, iced coffee, water, electrolytes, and post-run snacks, and you bring the willingness to show up!

This week’s workout: 300m repeats at 5K effort with 100m of smooth jogging between reps.

Short intervals, big purpose. These early-season efforts aren’t about speed for speed’s sake, they’re about waking up turnover, building efficiency, and sharpening focus. By holding controlled 5K effort across short reps, you train your body to stay relaxed under tension, something you’ll rely on across every phase of marathon prep.

Why this matters for marathoners:
✔ Builds aerobic strength with minimal fatigue
✔ Improves running economy (how efficiently you move)
✔ Reinforces rhythm and form before long tempos arrive

We hope to see you on the track!
