I will embark on one of my biggest sporting challenges to date when I attempt to teach comedian Frank Skinner to swim, starting next week.
Frank is a non-swimmer with a massive phobia of being in water so for Sport Relief, which begins on March 23rd, his aim will be to swim a width of the new Olympic pool, which is 25m.
It's a big challenge and Frank might not even get in the water during his first lesson, but I will be receiving help from a swimming teacher and he will also be having therapy to help combat his phobia.
Getting him over this fear and then teaching him to swim are two massive hurdles. It sounds so silly when you look at people like David Walliams who swam the channel and Eddie Izzard, who ran 43 marathons in 51 days, but in a way, this is almost a bigger challenge.
Learning to swim is one thing but he has got to overcome his phobia too and the anxiety that goes with it. He has got to be able to trust us and know that we are not going to let him drown.
His fear is an irrational one in many respects. Water can be dangerous but the real danger comes in rivers, lakes and the sea, places where other external factors such as temperature and tides have a bearing.
We will be starting in a small, quiet pool just to get him used to the environment and will be taking little steps with regular lessons.
I hope what Frank is doing will act as a big inspiration to other adults, with one in five in this country being unable to swim.
I was delighted to hear about the pupils at Westbourne Sports College, in Ipswich, who are going to be Field of Play Team Members at the Paralympics.
It will be an incredible experience for them and they will get the chance to see some of the greatest Paralympians on the planet.
Watching it on TV is one thing but actually being there you realise how fast the athletes are actually going.
I have been to events before and watched the 5,000m and 10,000m races. On TV, the athletes make it look so easy but I know I would not be able to keep up, even in just two or three strides, going full pelt.
Then there is the noise, which seems to follow the athletes around the stadium.
The pupils won't be the only volunteers at this year's Games either, as my mum, Deedee will be a volunteer at the swimming events.
Over the years she has done so much for other people as a swimming teacher, secretary of my local club and at Sussex County Swimming Association, never mind ferrying me around.
She will be looking after the officials during the Games and I am really proud of her.
