I'm assuming so - as I've recently discovered treadmill running is a lot easier than real world running (and I'm only road running - it's not as if I'm hitting the trails or anything)
I've not done Park Run in a few weeks due to work and the like, so I'm hoping to be able to make it next week - it'll be interesting to see what kind of time I can pull over 5k - previously I was just under 25 mins, I'm hopeful I can hit something closer to 20-22 mins as that'll give me the confidence that I can complete the 10k in August sub 40 mins (though I was previously hoping to be able to achieve sub-50)
