4x400 meters, 2:00 rest between rounds
so 11:23 (iffn' my maths are right).
Interesting. It's a route near my house . . . 400 out, 400 back. Slight uphill out, slight down back.
Still . . . BIG drop off in the third round . . . actually outran my legs and my lungs on that one. Usually it's one or the other
