Progressive run, 25min

Workout: 15min zone 1, followed by 10min zone 2

What is the goal of this workout?

1. Improve your aerobic shape: Progressive runs in 'zone 2' running are a great way to improve your aerobic shape.

Guidelines

Don't push too hard! Zone 2 should still feel comfortable. This is a pace you should be able to sustain even longer than the marathon distance. A good way to judge whether you are not running too fast is that you should still be able to talk while running.​
