I’ve had a few weeks break from running due to holidays/ hot weather . Have been repeating W9 of the app to consolidate and improve my speed . However, after a space of nearly 3 weeks found I had lost some of the fitness and struggled with a 30 min run and especially breathing trying to catch my breath( haven’t experienced this before)
My plan was to repeat say W5 of the app onwards as a strategy.
Any views/ ideas/ comments appreciated?
