Cardiac drift test

I did another drift test tonight. I'm very pleased with the results! Only 3 weeks after my previous one, I've made quite a gain in fitness. This is after my concerns that the 55 mile week had taken the edge off me. It's also only 2 days after an 18 miler! It would appear from the results that my marathon pace is now 8:12/mile, a pace I can maintain for over 9 miles with no increase in heart rate (my warm up was a little warmer than intended - 8:15/mile!).

This was just the encouragement I needed. BT rocks!

1.5-mile continuous laps. 1 mile warm up/cool down not included

Lap	Lap time	Mins/mile	bpm
1	12:23	8:15	138
2	12:19	8:12	141
3	12:18	8:12	142
4	12:20	8:13	141
5	12:15	8:10	141

For comparison, here's the results from 3 weeks ago:

1.5-mile continuous laps. 1 mile warm up/cool down not included

Lap	Lap time	Mins/mile	bpm
1	12:56	8:37	135
2	12:34	8:22	140
3	12:42	8:27	141
4	12:40	8:26	140
5	12:35	8:23	141
