This Sunday morning, my intention is to get up at the crack of dawn, watch the Chinese Grand Prix and then settle down to watch the London Marathon. How very couch potato of me.
Jo Swinson, Liberal Democrat MP for East Dunbartonshire, will also have the marathon on her mind. Although she won't be on her couch - she'll be queuing up at the start ready to run the 26 miles for Leukaemia and Lymphoma Research.
These last few months, not only has Jo been working silly hours as an MP, and training in all weathers for the marathon, but she's been doing her best to raise a significant amount of money. Her target was £100 for each of the 26.2 miles and she's smashed that by sending hand written "blue letters" to friends and colleagues asking for donations.
If you look through the names on her Justgiving page, you'll see that she's had warm words written about her by MPs from other parties. I like that generosity of spirit.
So, Jo, all the best for your wee run round the streets on Sunday. The couch brigade will be cheering you on every step of the way. I am completely in awe of all the work you've put in preparing for this, and I know it's a cause you believe passionately in.
If you can, please sponsor Jo here.
