Fartlekish-10km

6:30am- Coool this morning, certainly cold enough for a t-shirt. Was in two minds what to do today (short sharp or long easy) ended up just hitting the bitumen and doing and extended "college" run. Work to Lane Cove-Longueville and Riverview College-return to work. This course has some nice hills there, that I wanted to surge up. After 5km I decided to throw in some 30/30s, ended up doing 6 reps and then did some 60/60s (4 reps). Finished with some 50m surges (lampost to lampost type stuff) and 1.5km warm down. All up 10km with average pace 4:39/km.
