Thats a great effort, well done.

And well done on sticking to your plan and finishing after 7 laps... it would have been so easy to do a couple more laps and then pay the price in needing a longer recovery time or even potentially risking injury

I've only discovered the 'Backyard Ultra' events quite recently, it is an intriguing concept of physical endurance and mental strength. The stop/start element alone must be really difficult to deal with.

Is this your first one, or have you done others like this before?
