I've grown accustomed to hiking hills, having lived in SE London for the last 17 years. 

For anyone who doubts the inclines, two of the hills I'll be running up come in at number 1 spot for cyclists looking to blow a gasket: https://www.broleur.com/top-ten-toughest-cycling-climbs-london-bergs/ (15 - 20% inclines)

My aim is to run it 3 times, and hopefully on the day feel I can stretch it to 4! This will mean running up 12 punishing hills over the course of about 90 minutes. 

Every school is struggling to find the funds to help maintain outdoor spaces for pupils to enjoy. Please give anything you can to help the Horniman Primary School (and see me suffer)!
