Marathon Plan

i would like to work up to doing 50 of them, in 36sec each. That’s 3min per 1km pace and 10km all up.
There is a 10km run as part of team in about 6wks time so would like to do that by before then.

weather is cooling, but the humidity is still the biggest thing that kills. Must have been 100% humidity this morning, was covered in sweat.
Fri morning, 4km run, before a 50min runnin tempo, faster efforts, maybe 150m done in 2 sets of 10 on a 60sec cycle. was acg around 21sec to run
