Three runs this week the first two were rubbish relatively speaking. I ran in the evening after particularly bad days at work and they were tortuous from beginning to end, heavy legged, heavy hearted, muggy weather.
I am not looking for sympathy I hope you understand sometimes it goes that way and I did still squeak out 9 and 10k respectively but they were slow and just teeth gritting from the get go. Loads slower than I would normally do that distance.
Well today I did a ParkRun just to shake the cobwewbs aways away (bearing in mind the tough 10k was yesterday) and I knocked 16 seconds off my PB! 16 seconds! I can't remember the last time I took a bite out like that; for a while I have been reeling it in but slowly-slowly then a big old bite! Pretty chufffed, not to say amazed. I just don't know what changed since yesterday except for the time of day maybe......
Anyways I think the moral of the story is those tough runs sometimes seem to go on for ages and ages but you just never ever know when suddenly it will, for no apparent reason, suddenly all just click back into place unlooked for.
A tough run is 100% better than no run however much it hurts at the time, there is always a good one round the corner (so far!).
