02072018 Intervals

It was an interval day, 10m warmup then 4 x 8 min zone 4 + 90sec recovery then 5-10 minute cool down.   Today was harder than usual, we were doing sub 10’s during the z4 sections and it was difficult.

RPE was a good 8 or 9 for me on this one and at this speed and timing it’s usually more 7ish.

But after doing 20 minutes on Sunday I imagine its carryover.
