Ran along the busway along Centennial Park to do these. Nights are pretty cool at the moment after all the Southerly winds over the last week. Almost lead to me wearing something more than shorts and singlet. I said almost!
The reps were 1:37, 1:32, 1:36, 1:35, 1:33, 1:35, 1:33, 1:34. All done with a 60 second jog recovery between each rep.
Did a 2k warmup and a 2k cool down after the session.
