RUN A MARATHON
If you can’t run to the bus stop, it’s probably not best to start off with a marathon. But, with enough training, you can get there. You don’t need to break a world record, you just need to finish. The London Marathon is hard to get into as it’s massively over-subscribed, but why not try a local event first? Most cities in the UK, and beyond, hold marathons, which you may find easier to get a place on.
