Every Tuesday morning Tiger Muay Thai organises a run to the Big Buddha in Phuket. The run is 4.2 km / 2.6 miles long and up hill all the way. You actually climb 1207 feet / 367 meters during the run, it’s hard. The record is something like 24 minutes!
I did it in just over 44 minutes, so in 2 weeks time when I try this again I will see if I can get a sub 40 minute time. This will involve running at some point, rather than just walking..
