Pretty typical tempo run, goal was 4 miles @ 6:41/mile.
Tempo Splits: 6:39, 6:39, 6:39, 6:37
Total Mileage: 6.00
Time/Pace: 44:24/7:26
Avg HR/Max HR: 148/176
Then power intervals on the bike.
Goal: 4x4min, 82-87%MHR, 70rpm
The 1 interval went off fine, avg HR 151, max 161, 71 rpm.
My heart began to race during sets 2 and part of 3, got upto 191bpm and 171bpm respectively, before it settled down again for an avg of 144 for the last set. Weird.
Mileage: 10.09
Time/Avg Sp/Max Sp: 40:00/15.1/23.7
Avg HR/Max HR: 142/192
I've experienced these HR spikes in the past, most noteably at last year's Turkey Trot. It is troublesome, but happens infrequently. I did have my heart checked out last year; i.e. stress test, cardiogram, and everything was acceptable. They found my resting HR of 47 to be curious, but normal for my activity level.
