A great fartlek and progressive threshold session to improve your running. Plus, the components that should be part of an effective run program, even though they’re not necessarily classified as “run sessions”.

Part of this episode is original content, and part of it is a preview of the full episode "Power Rankings - Our top-5 run sessions to improve triathlon running performance" (release date 5th of February 2026).

TOPICS COVERED IN THIS EPISODE:

Mikael’s favourite Fartlek run
Jack’s descending threshold session
Why and how to do strides and hill sprints
When is running off the bike a good idea? (Even though a lot of the time it isn’t a good idea, and it’s probably overused in triathlon)
How hilly is a “hilly endurance run”?
