Oh boy, that was a toughy!
I was warned by several people that running a mile every hour, on the hour, for 24 hours is extremely hard work. I'd naturally assumed that the lack of sleep would tough, but in fact, the stop-start nature is especially hard on your muscles. The short period of rest you get between each run does not make up for the lack of training to run a marathon distance. Each time you run you are compounding the inflammation in your tissues that naturally follows exercise, instead of allowing time to recover. Unsurprisingly, I found the runs after a half marathon distance to be quite tough. As the night wore on, it became, to be frank, painful. Storm Barbara didn't help, with several miles run in heavy rain and strong winds.
Thankfully, I had Christine to run with, which kept both of us distracted during the runs. It also helped enormously to see the incredibly generous donations of so many people. Our charities will already have received this money allowing then to continue their vital research into finding cures for motor neurone and Alzheimer's diseases.
Happy and relieved to have completed Phoenix 24 with a twist. Don't think I do that again.
