Description

Break the four-hour marathon barrier with a structured 16-week training plan built for runners training in hot and humid conditions.

The Mister Finn 16-Week Sub-4 Hour Marathon Training Plan for Hot Conditions is designed for experienced everyday runners who already have a solid running base and want to complete 42.2 km in under four hours.

To run a sub-4 marathon, you need to average approximately:

5:41/km

or

for the full marathon.

This plan combines easy running, threshold work, marathon-pace sessions, long runs, fueling practice and recovery while showing you how to adjust when heat and humidity make normal pace targets harder.

Built for hot conditions

Marathon pace changes when the weather changes.

A pace that feels controlled in cooler conditions can feel much harder in high heat and humidity.

This plan shows you when to:

• Slow down
• Run by effort instead of pace
• Extend recovery
• Reduce marathon-pace volume
• Move a workout to a cooler time
• Use a treadmill
• Adjust long runs
• Change your race-day strategy when conditions demand it

The goal is not to fight the heat.

The goal is to keep the training productive enough to arrive at race day ready.

The goal

Distance: 42.2 km / 26.2 miles
Training period: 16 weeks
Target time: Under 4:00:00
Target pace: approximately 5:41/km / 9:09/mile
Running days: 4 per week + optional recovery run
