I've just done something stupid. I reserved a place at the Manchester Marathon next year - April 2019.
Yesterday: I ate 2 chip barmcakes for my lunch. I had two burgers for my dinner. Last night I drank a bottle of wine. According to government guidelines that makes me a binge drinker.
My skin is blotchy. I've got pimples on my chest. My mouth tastes revolting. I've got zero energy - I feel so rough this morning I doubt I can get down the stairs without my heart pounding.
I'm 45 years old. Overweight, unfit, eating badly, fundamentally very lazy. Heading for diabetes and heart disease I imagine.
So the marathon. I'm not going to tell anyone in real life (because they'd kill themselves laughing) and I'm not going to think about it just yet. It's 50 weeks away And I need a much better frame of mind than the self-destructive lazy way of thinking that I have right now. I'm vaguely thinking I'll start with some beginners yoga (YouTube Yoga with Adrienne) and meditation (Headspace app).
And sort out my diet. I like Michael Mosley's books and I like Mediterranean-style food, so that lends itself to things like vegetables, good fats, meat, fish, lentils, beans. That's doable - it has to be tasty and realistic.
Then I'll download the couch to 5k app I guess. Then maybe do some of the 5k park runs. Then think about 5k to 10k.
I might not do the marathon in 50 weeks time. I might not even like running. The point is the end goal and the deadline and having something to work towards. I've also fancied trying dance classes or ice skating, but have been too lazy to do them.
Anyone up for joining me in a mental, diet and fitness overhaul? You don't need to sign up to anything stupid like I have
