London to Paris in 24 hours

a friend of mine  is cycling with a small group from London to Paris in 24 hours on 11th-12th september. it's to raise money for Cancer Research UK. typically a four-day cycle ride, it's going to be a challenge, but he's a beast on the bike so i have faith. here he is riding through the alps.n202905161_34135408_1308
