Been fighting something off the last couple days. Not feeling sick but picked up a cough that I can't shake. Schedule called for 18 miles today but based on the results of a couple HR tests that I ran last week I'm feeling that mileage might be the problem. If thats the case then more miles are for sure NOT the solution. The body said 'sleep' and today I was wise to listen.
I guess technically it's not the miles that might be the trouble but rather the intensity that I have been running them. I haven't had a chance to chart the data from the Conconi test but the results did show an obvious plateau for me at 157 BPM. Brian's data was less conclusive. There were two flat spots on his curve, one at approx 150 and another near 160. I have the raw data at work so my apologies for not being more accurate with the report at this time. Anyways, one of the arguments against the validity of the Conconi test is that not all people show an obvious deflection which is what we see with the data from Brian and I.
The point is that whatever the knocks against the test FOR SOME PEOPLE, it yielded a nice flat spot for me. And I have been training above this line for basically the last 20 weeks.
I also calculated my 70-80% heart rate targets using my resting heart rate, max rate and the Karvonen formula and came up with a range of 149-160 BPM.
Last week's long run shows me with an average heart rate of 157 BPM over 16 miles BUT only because the first 5 miles I was well below average. Average heart rate for the first five miles was 147 which means that I ran well above average for the last 11: average BPM 163.
If Conconi test shows anerobic threshold at 157 BPM, which not coincidentally is EXACTLY 85% of my measured max heart rate of 185, then the only thing I can conclude is that I have been running too fast too soon.
What this means for my training from here on out, I can't say except that it won't be more of the same.
