Well, I am flabbergasted with myself! Yesterday I completed the dreaded one I struggled with the second 8 minute run on the previous session so really wasn't sure if I could do it. I had an awful stitch kick in at about the 16 minute mark but couldn't bear the thought of giving up at that point so managed to continue until the end. Had a face like a beetroot by the time I'd finished.
Those shin splints are still twinging away but I do an ice massage for 20 minutes on each leg when I get in which seems to be stopping them from getting any worse.
I started the 5:2 diet around the same time as C25K and have lost 19lbs so far (in 9 weeks though rather than 6, as I had to stop running for 3 weeks due to the shin splints) so feeling rather happy at the moment. The lower half of my legs are even starting to look like proper runners' legs! Not sure about the top half yet though
One thing I wondered about was Laura's suggestion of breathing in through the nose and out through the mouth. I'm breathing in and out of my mouth! Don't seem to be able to get enough air in if I keep it closed lol. Do other people breathe in through their nose?
