Well, I've made my decision. I've been suffering from hamstring problems for a couple of months, though it's been a real problem since a half marathon at the beginning of April, where I ran the last five miles or so in increasing pain and with increasing difficulty. Another topic, but I think the problem was caused by me thinking I didn't need orthotics in my shoes any more and taking them out.
I was signed up for the Milton Keynes half on Monday, and had hoped I'd be well enough to take part. As a last push, I saw a new sports physio on Tuesday and had a thorough assessment and going over. He helped a lot, but it's not completely healed yet, and I made the decision yesterday to defer my entry. I'm glad that's done, but still a bit disappointed. I just didn't feel confident that I wouldn't make it much worse again - 13.1 miles on a sore hamstring didn't feel right.
On a more positive note, as a result of my call for advice at the club, I now have a coach! I had a session with her on Wednesday, where she filmed me running for analysis, and talked over a training plan for this year. Somehow, it's based around a spring marathon next year! She's pointed out some things that need correction, but says I should fix one at a time. So my first task is to increase my running cadence to 180spm. I've also got some exercises for glute activation and general strength. Together with the exercises the physio gave me and my new Pilates classes, there's a lot going on, and I feel positive about where I'm going.
Anyone else had to make hard decisions like that?
