... so I did it!! Just back from my third run of week 9. Can't say it was easy but there was no way I was going to stop on this one. Even overtook a couple of really slow joggers which made me think back to my first week. I have definitely progressed. So pleased with myself. Haven't made it to 5k yet but that's something to aim for now. Have also lost half a stone which is great. A bit to go yet but a good start.
Thanks to everyone who posts and encourages on here - it's the best forum I've come across.
