Road running intervals 17:11  4.8 km (3:35 / km) +42m 3:26 / km
Hyde Park. Intervals (4 x 1.2 km, off 3:00 recovery) - splits 4:20, 4:14, 4:23, 4:14 (average split 4:18, average pace 3:35/km).
Pretty good session - longer intervals than recently which felt tough. The returns felt easier than the way out (as shown by the splits) - looks like there's a net 10m height gain on the 1st/3rd ones, which I definitely feel! (I'm really not used to any slopes these days...)
