Ok, so just couldn’t work out why after this run, I’d only travelled about 1.7km instead of the 2.1km that I’d been doing in W2.
Turns out doing maths immediately after a run is stupid...! Leaving it for 20 minutes then doing the maths again makes it all become clear.... less actual exercise time/distance, more intensity! D’oh!
So I was a bit dubious about running for 3 minutes solid.... don’t think I’ve done that in nearly 12 years since leaving the RAF! But, through gritted teeth... each 3 minute run came and went without incident.
The thing I thought was shin splints doesn’t appear to be... each new run seems to feel a bit easier on the shins.
Just that horrible “calves feeling like lead weights” hurdle to keep getting through.... does this stop after a certain amount of time running or is it something that you always just have to grit your teeth through???
