Road running warm up/down 28:08 [1] 5.72 km (4:55 / km) +68m 4:38 / km
ahr:165 max:170
Battersea Park. Intervals (6 x 1 km, off 2:30 recovery) - splits 3:31, 3:30, 3:43, 3:31, 3:47, 3:32 (average 3:36).
Slight disaster, with stomach issues meaning I had to pop into the bushes during the 2:30 recovery after both the 2nd and 4th intervals (!), which led to the 3rd & 5th ones feeling really tough, especially as these were into a fairly strong headwind (although I'd pushed through this on the first one) - but somehow did the 4th & 6th ones pretty well, on target pace, so shouldn't be too disappointed really.
