It seemed harder today. I think running 600s is in some ways harder than 800s, since I'm aiming at 17-18sec/100m at 600m pace compared to around 20-21sec/100m at 800m pace.. and for 300's, 14-15sec/100m pace.

2 x 600m - 1:47, 1:51
2 x 300m - 44, 44Roya pushed me on the last 100m on the 300s. She can definitely run in the 15s in 100m, very impressive.
