After a couple of years of office banter, me and John Brown (@brownbare) have decided to once and for all find out who is the better man.

We’ll be donning our speedos and heading to Hampstead Heath Swimming Ponds next Tuesday morning (17 May) at 730am for a 100m freestyle race before work.

It’s less than five weeks to go to the Speed Three Peaks Challenge. Our duel will be one of a series of fundraisers along the way to help us raise £3,000 for Macmillan Cancer Support.

If you fancy showing your support head to our Justgiving page; John has said he’ll wear a bikini if we raise £250. I know better than to make such rash commitments.

The Ponds are one of London’s hidden gems and are one of the capital’s few wild swimming locations. If you fancy joining us we’ll be heading to the Mixed Pond.
