Intro: Based on Ben Is Running’s video Why I Run TWICE a DAY! (Benefits Of DOUBLE RUN Days), here’s what makes this approach worth testing. The full video has plenty more detail, but we’ve distilled the essentials so you can implement the workout right away.

Key Points:

• Break up mileage: Instead of tackling one 20 km effort, divide it into two shorter runs (10 km each). This makes your daily volume feel less overwhelming and cuts down on mental resistance.
• Less joint/shin strain: Splitting your distance means avoiding the wear that comes from a single long run. This is especially valuable if shin splints have been a problem for you.
• Active recovery: Use your morning session as a recovery run with minimal intensity, then save your peak effort for the evening.
• Fitness boost: Two daily sessions accumulate more weekly volume over time, building VO₂-max and race readiness without racking up injury risk.
• Practical tip: Trust your body’s signals on easy runs rather than chasing pace numbers; save the precision work for interval sessions in the evening.

Workout Example:

• Morning run: 16 km (10 mi) at a comfortable, conversational pace (roughly 4:30–4:45 per km, but don’t fixate on the watch).
• Evening session: 20 × 300 m repeats at hard intensity, 30 seconds recovery between efforts. Dial back the repeat count if it’s too much for your current fitness.

Closing Note: Test double-run days, customize the session volumes and distances to match your own abilities through the Pacing app, and you’ll likely see gains in fitness. 🚀
