Description

Prepare for your first marathon with a clear, realistic 20-week training plan built for runners training in hot and humid conditions.

The Mister Finn 20-Week First Marathon Training Plan for Hot Conditions is designed for everyday runners who already have a basic running foundation and want to complete their first 42.2 km marathon without chasing a finish time.

This is not a couch-to-marathon plan.

It is for runners who can already handle around 10 km and want enough time to build endurance gradually, practice long runs, learn fueling and hydration, and prepare for the demands of marathon day.

There is no required race pace.

No pressure to copy someone else.

No need to race your training.

The goal is simple:

Build the endurance, confidence and race-day skills to complete your first marathon.

Built for hot conditions

Marathon training in heat is different.

Long runs mean more time exposed to temperature and humidity.

That affects pace, effort, hydration, recovery and fueling.

This plan shows you when to:

• Slow down
• Run by effort instead of pace
• Add walking breaks
• Move long runs earlier
• Plan shade and water access
• Shorten a session
• Use a treadmill
• Adjust when conditions become unreasonable

The goal is not to fight the weather.

The goal is to keep training consistently enough to reach marathon day ready.

The goal

Distance: 42.2 km / 26.2 miles
Training period: 20 weeks
Running days: 4 per week
Target time: None
Goal: Complete your first marathon with control and confidence
