Literally pretty much exactly the same as me. Got a ballot place and knew it was too goo to turn down so started running at the start of July last year and couldn't run a mile without stopping, kept at it and absolutely hated the first 4-5 weeks then something just clicked and I found myself weirdly starting to enjoy it.
Over 900 miles later and 5stone 5lb lost in weight and I really cannot imagine my life without the routine and running now - it has completely transformed my life.
Advice for any beginners - just stick at it even when you can't be bothered. It is such a rewarding sport (and very mentally challenging at times).
