MARATHON 42.2k - Target exactly 3h30!
This plan shows key weeks from the 14-week program. Intermediate weeks follow the same pattern with progressive intensity.
Training tips
- 1.VO2 max = ~18 km/h. VO2 max at 90-93% max HR on 400-1000m
- 2.Anaerobic threshold at 85-88% max HR on 8-15 min
- 3.Marathon pace = exactly 5 min/km - master it
- 4.Recovery and rest are as important as hard training
Frequently Asked Questions
What level is needed to target 3h30 on a marathon?
This is an advanced goal. You must run 10k in under 40 minutes (4 min/km pace) and have completed a fast half marathon or full marathon. You also need at least 100 km per week training volume.
How do I adapt nutrition for running 3h30 (ultra-fast)?
At this speed you burn lots of energy. Take 60-90g carbs per hour (gels, drinks). Start at 30 minutes. Hydrate well (500-600ml/hour) without over-drinking. Test on 2+ hour long runs.
What's the pacing strategy for 3h30 (5 min/km)?
Km 0-10: 5:05/km (slightly slow to conserve energy). Km 10-30: exactly 5:00/km (steady pace). Km 30-42: 4:50-4:55/km if you feel fresh. This is an athlete's marathon - every second counts!
