BackYard concept really isn’t hard to grasp 🙂 , you just have to run 6,7 kilometers in one hour. And start again every hour. Until in the end there is only ONE left … !!! Most probably after hundreds of kilometers and dozens of hours : in 2019, Chartreuse BackYard ended after 41 hours and 275 kilometers with Maxime GAUDUIN as the only official finisher, all other participants being declared DNF.
But Chartreuse BackYard is also the opportunity to go for your OWN challenge hour after hour : run for the 1st time a HALF-MARATHON ? a MARATHON ? 100 KILOMETERS ? 100 MILES IN 24 HOURS ? Take up YOUR personal challenge … in any case at the end there will only be ONE left…
