John is hoping to raise £900, with his London Marathon running efforts in support of Devon Air Ambulance. If you would like to help John reach his goal you can support him through his fundraising page.

If running in a marathon is not your thing, there are many ways you can help our charity.

Want to get involved yourself? Here's how to set up your own event. Or you can find out what some of our other fundraisers are doing in support of Devon Air Ambulance.
