Fartlek day

Morning: Fartlek 8*2/2min. (on: 5.42-5.18/mile / off: 7.30-7.00/mile) + warm up and cool down = 8+ miles (7.22/mile).

Couple of faster (on-)runs felt really great, but on the contrary two of them felt quite heavy even if I was running them on a moderately flat course. Still farting during & leking made me happy.
