Well, today I did my first run of Week 4! I should be feeling great ... onward and upward and all that ...
It probably seems a bit lame but I have found the transition from Week 3 (run for 3 mins - walk for 3 mins, etc.) to Week 4 (run for 3 mins - walk for 1.5 mins - run for 5 mins - walk for 3 mins, etc.) a bit of a struggle. Probably the cumulative effect of longer runs and less rest.
I've ended up slowing right down on the run just to complete the running bits - and it feels like I could walk faster!
Any tips on what to do differently?
