Week five started with jogging for five minutes, walking for three, jogging for five, walking for three and jogging for five.
I had expected all the week five sessions to be the same which is why session two came as a shock: jog for eight minutes, walk for five, jog for eight.
I survived, just, and then session three really knocked me for six: jog for 20 minutes. Wait, what, jog for twenty minutes?
The thing that shocked me more than the leap from five to eight to 20 minutes within the space of days, was the fact that my legs, lungs and heart didn’t let me down.
