The full erg marathon (42,195 metres) is one of the most gruelling endurance challenges in indoor sport. Lasting 2.5-3.5 hours, it requires months of base-building, meticulous pacing, a nutrition plan, and extraordinary mental fortitude.

Coaching Notes
- +Your marathon split should be roughly 20-30 seconds above your 2K split.
- +Create a nutrition plan: water every 15 min, energy gel or food every 30-45 min.
- +Use a seat pad — prolonged sitting causes significant discomfort without one.
- +Break the marathon into 8 segments of ~5K rather than thinking about the total distance.
- +Have entertainment ready — music, podcasts, or even a screen for video. This is as much mental as physical.
