I too am back in that place where a 7 mile run feels like torture. It's true what they say - fitness and endurance can take months and months to create but it only takes weeks to lose (or less depending on the amount of beer and pizza consumed). That said, I have A LOT of work to do in the month of September if I'm going to be remotely ready for the Cave Creek 50K in October. Hopefully the weather will begin to cool down and longer runs will be more inviting.
So to all of you out there who are sore today from your workout, I say "push on". Take 10 minutes, stretch and resolve to do it again tomorrow - I guarantee, it gets better.
