10x1/4-mile intervals at Sugarhouse Park with 90 seconds active recovery between each. Warmup (around 2 miles) didn't feel particularly good, as my back pain seems to have returned (same spot--just left of my tailbone along the top of my pelvis) and was causing a "hitch in my giddyup." It started feeling a little better near the end of the warmup. Splits were as follows:
1: 79 (5:17/mi) (AHR 156/MHR 167)
2: 79 (5:16/mi) (166/178)
3: 72 (4:49/mi) (170/177)
4: 77 (5:09/mi) (177/184) (this was up the hill on the northeast corner near the rose garden)
5: 77 (5:09/mi) (168/175)
6: 79 (5:15/mi) (178/182) (finished up the hill on the southwest corner)
7: 77 (5:10/mi) (173/181)
8: 74 (4:55/mi) (172/178)
9: 82 (5:28/mi) (175/185) (finished up the hill on the southwest corner)
10: 73 (4:53/mi) (175/181)
1-mile cooldown. Solid workout--some of the best 1/4-mile splits I've seen in a long time. |
