Intro

A breakdown of The Welsh Runner’s marathon long-run vlog. The key takeaways to apply today. Watch the full video for context and tips.

Key points

  • Nutrition: a high-carb lunch the day before tops up glycogen. Keep dinner light. The morning of, simple carbs work: oatmeal, banana, coffee.
  • Fueling on the run: pack gels and water, rehearsing the exact amounts and intervals you’ll use on race day. Start fueling before fatigue sets in.
  • Gear: train in your race-day shoes (usually lighter) to break them in. Start long runs on soft surfaces to limit impact, then add road sections later to adjust to pavement.
  • Practical tips: test how you’ll carry gels (safety pins through shorts or a flip belt both work). Pick a route with toilets and water access.

Workout example

  • 20-mile long run (around 32 km) on flat, forgiving terrain to match a flat marathon.
  • First half on softer surfaces to limit impact stress.
  • Layer in road sections in later long runs to adapt to pavement.
  • Fuel and hydration: a gel every 45-60 minutes and water regularly. A flip belt or pinned gels keep hands free.

Closing note

Try this 20-mile long run, adjusting distance and pace to your plan in the Pacing app.
