okay it took me a few days longer but I have just been out there today and have run my last run of couch to 5k program.
After the usual confusion that you don't actually do 5k in 9 weeks, and with my body groaning at me to stop I "crossed the line" and was told well done for the last time.
So what is next well I think it will be actually getting to 5k altogether whilst running, but this Saturday I am going along to park run, apparently you can catch yourself a panther if you are lucky.
