Marathon Plan

Tuesday
10km early run. 40min, didnt feel too flash, wore some compression pants to avoid chaffing but they felt restrictive around the hip flexors and hip height felt lower?
Right after, 50min of running circuits
Again, very muggy and lost a couple kg even with drinks during.
Feet are a bit sore around the edges of the heels (will massage) and right foot 2nd toe nail is killing… it was bad this time last year too, lost the nail then.
