Just 3,400 ascents to do
If you've ever got cross at a child for thundering up and down the stairs, think of what it must be like in the White household.
Eleven-year-old Josh is climbing the stairs 3,400 times - the equivalent of 8,848 metres, more or less, which is the height of Mount Everest.
He set off a few days ago, with the intention of raising £100 for Dartmoor Zoo, which is closed during lockdown, yet still costs around £45,000 a month to run, even with running costs cut during the crisis.
It's not clear whether running down the stairs counts as part of the stair climb - or whether he will have to do a further 3,400 trips to get down again.
Josh has a JustGiving page called 'Everest Stair Climb for Dartmoor Zoo'. You can donate here: https://bit.ly/2KmH38g
