Intro
RUN SDJ’s Epic 26KM Run Through London’s Heart | Paris Marathon Training Week 6 offers excellent insights for long-distance training. We’ll walk through the key elements so you can test-drive this session yourself. For the complete experience, check out the full video.
Key Points
- Long-run focus: A 26 km (≈16 mi) long run with no set pace — perfect for building endurance and mental toughness. This type of aerobic-focused work forms the foundation of marathon training, though it works best alongside speed-focused sessions. To understand how speed training fits in, explore our guide on Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them.
- Target pace: roughly 5:50–6:00 min/km (≈9:20–9:40 min/mile) — a sustainable, aerobic tempo. This conversational intensity differs significantly from the pacing demands of shorter, faster races. To explore race-specific pacing strategies, see Mastering the 10K: Proven Training Plans, Pace Strategies, and How a Smart App Can Elevate Your Performance.
- New terrain: Running through the River Lea, Olympic Park, Victoria Park, Thames Path, Tower Bridge, and the London Eye breaks up the miles and keeps your mind sharp.
- Nutrition experiment: A Kendal Mint Cake bar (85 g, ≈83 g carbs) divided into six pieces and consumed every 30–45 minutes provides steady fuel without digestive stress.
- Practical tips: Stay relaxed, use landmarks for pacing markers, watch for pedestrians and cyclists on London’s busy streets, and maintain consistent nutrition and hydration throughout.
Workout Example
This session prioritizes “time on feet” over hitting specific splits. It’s foundation-building work — the kind that develops the aerobic capacity a marathon requires, which operates by different rules than the high-intensity training featured in Mastering 5K Speed: Proven Interval Strategies to Cut Minutes off Your Time. Here’s the breakdown:
26 km (16 mi) Long Run – No Pace Target
- Start at a relaxed 5:50–6:00 min/km (9:20–9:40 min/mile) pace.
- Run through varied routes (river paths, parks, city streets) to keep the mind engaged.
- Every 30–45 min, consume a 1/6 portion of a 85 g Kendal Mint Cake bar (≈13 g carbs per piece).
- Aim to finish in ~2 h 45 min to 3 h (depending on fitness).
- Finish with a cool‑down walk or light stretch for 5‑10 min.Closing Note
