Warmed up with 2.25 miles. Supposed to do 4 X 3/4 mile repeats at 5K pace (6:15/mile) with 1/4 mile jog. I actually try to run these a little faster than 5K pace. Ran 1st a little fast (5:55 min/mile). Settled in on 6:00 min/mile pace for the next 2. I was holding a 6:00 min/mile on the last one when I was stopped by a train at the 0.6 mile mark. Decided to throw in 1 more repeat just for good measure. Was able to hold 6:00 min/mile pace the entire way but it really started to hurt. Finished with 2.4 mile cool down. |
