I feel like resisting this but also can see the benefits too. I want to bring my running down to 30 minutes for a 5k, which I'm told is quite a ask. I've just got it down to 33:38 so am not too far off.
We're thinking of moving to 10k now. I thought I wasn't ready but was so surprised as to how easy an extra 1k was to add to the run. We're going to run / walk the additional 5k I think this doesn't make me feel quite so nervous.
Wish me luck.
