A family from Bridgwater have already smashed their fundraising target by doing a sponsored half marathon in their back garden.
Dad Levi and Dexter, 6, are doing it to raise money for Taunton's Musgrove Park Hospital during the lockdown over five days.
They had hoped to raise £100 but have already passed £500.
Levi said: "We have worked out the length of our garden from shed to decking area to be 94.5 feet.
"We have done our research and a half marathon totals 69,218 feet so therefore we need to complete 733 lengths over five days."
