AM-Easy-medium pace aerobic run for 7.5 miles with an acceleration for 1 mile up to 5:18/mi. Did this on the treadmill for an aerobic maximum pace test and to also get a grip on where my LT pace is at now. Ran at max aerobic around 5:50 at 2% incline with a 145-146 THR. Funny thing about this test was that the heart rate was actually going down after 20 minutes instead of going up for a given pace. I think this might be due to a number of things like just plain finally starting to warmup finally but someting tells me there are other factors also. Normally after 20 min you would expect some cardiac drift as this was always the case in the past. Is it possible that the body is making it's aerobic shift later in the run than usual. Anyway it's too much detail to tink about right now. PM-4.5 miles easy at 8-7min/mi. Neighborhood. Just kinda zoned through this one. |
