Five times... er...

Eaton Park efforts again. Same route/loop as last week, but just five laps of the grass this time with 1:30 recovery. It was initially billed as "somewhere between 800m and 1km" but after the first lap (which I did in 3:07), that was hastily revised downwards. Someone's GPS suggested 0.42 miles, which we roughly converted at the time to 640m, and GMaps agrees with the properly worked out conversion which is 675m.

My times were 3:07, 3:07, 3:10, 3:11, 3:04. It felt sustainable for the lap, but I don't think I could have done 1.5 or 2 laps continuously at that pace. Mark came along too and did the first one at 3:20 (7:52/mi), then the next 3 progressively a bit slower, and sat out the last one. Fair enough, for his first Thursday session!

Three minutes for 675m = 7:09 per mile, with +/-5 seconds per lap equivalent to +/-12 seconds per mile, so that puts my reps between about 7:20 and 7:35/mile. I am pleasantly surprised by that - I would have said around 8 or just below. To put it in perspective, my 5k PB of 24:33 is 7:54/mile.
