you expert level
my zone 2 is ard 8min/hr or slower
7min/km will easily be in zone 3 liao
my fastest after 10km of zone 2 is only 5min/km for 1km.
so if i am to brisk walk, which i had done 10-12km, i had to do it at 9-10min/km. if i have to lower the time, i have to mix it up with runs at ard 7-8min/km.
maybe next time i should try brisk walking for HM and test how long will i take.
Problem is that though walking can be done at a lower speed than running (duh) with a more natural gait, it is at a higher energy expenditure per km.
(racewalking 50km burns nearly 2 times the energy vs running a 42.2k, can just do the conversion)
So trying to briskwalk the FM really need to fuel well, coz you'd expend more energy than running.
Just that also if walk relatively slowly, it is also possible to just turn to a high percentage of fats burning, so also can be maintained......just not so slow that 7hrs also cannot finish can liao.
