Approximately 30,000 people will take on the London Marathon this Sunday.
These brave (and very fit) souls will run 26.2 miles (42.2kms) through the streets of our capital, in aid of very good causes.
I haven’t ever run one. And, to be honest, I doubt I ever will. But last weekend my sister completed her first one. She ran the Brighton Marathon, for Cancer Research UK, in under four hours (3.53.47 to be precise.)
My contribution to this marvellous effort? Well, when she started training months ago I said I would watch, drink some wine, and have a bottle of pink fizz for her at the finish line.
