I am cycling the "Dragon Devil", a 300km (186 miles) loop over evil Welsh hills. Over the course of the day I will ascend 4,350 metres, or 14,272 feet, roughly half the height of Everest.

This is objectively stupid, but it is for an extremely good cause: Macmillan Cancer Support. Here is their blurb:

At Macmillan, we give people with cancer everything we’ve got. If you’re diagnosed, your worries are our worries. We’re doing whatever it takes. But without your help we can’t support everyone who needs us.Donating through JustGiving is simple, fast and secure. Your details are safe with JustGiving - they'll never sell them or send unwanted emails. Once you donate, they'll send your money directly to the charity. So it's the most efficient way to donate - saving time and cutting costs.

That's the pitch. I would be very grateful for anything you can spare. Thank you.
