Intro

This is a quick summary of HURTWOOD 50k RACE DAY! | ARC of ATTRITION Series Ep 2 from Run4Adventure. It’s a great watch — we’re breaking it down so you can try the workout today. Be sure to check out the full video for all the details.

Key Points

Treat the ultra as a training run: start easy, walk steep climbs to save leg energy, and finish strong.
Nutrition strategy: pre‑load high‑concentration electrolytes and aim for ~45 g carbs per hour (one pouch every 2 hours).
Pacing: start steady, keep effort easy on the up‑hills, then pick up the pace on the flat and downhill sections.
Practical tip: use checkpoint fuel (flapjack, peanut butter sandwich, crisps) to keep energy up, and stay positive with supportive marshals and fellow runners.

Workout Example

Hurtwood‑style 50 k training run (≈31 mi)

Warm‑up – 1‑2 mi easy on flat trail.
Hill section – Walk or very easy jog on steep climbs (save leg energy).
Mid‑section – Run at a comfortable, steady effort (≈65‑75 % of max HR).
Checkpoint nutrition – Every 2 hours, take a Precision Fuel pouch (≈45 g carbs) and a salty snack; stay hydrated with high‑electrolyte drink.
Flat & descent – Increase pace on downhill and flat sections, aiming to finish strong.
Finish – Aim to finish the 50 k in under 7‑8 hours (adjust based on your own pace).

Tip: If you’re not doing the full 50 k, apply the same structure to a shorter trail run: start easy, walk steep hills, fuel every 2 hours, and finish with a stronger effort.
