Hi everyone, I have a situation i’m quite clueless about.
3 months ago I started triathlon training again after a hiatus of serious training of 2 years because of work, injuries etc.
My training consists of only building aerobic miles, and especially in running being very carefully.
In these 3 months, I’ve seen a very big drop in heart rate at the Same pace or power output and have seen decent FTP gains from 275 to 310 watts. I used to run 5:10/km at HR 155,now it’s 135 (using Barry p plan of 6 easy runs per week). Used to ride base zone 2 miles at 125-145 bpm and now 130-135 max for 70% ftp.
However, I’ve noticed that I can’t get close to my previous max heart rate any more. Few years ago, I would do my 20 min FTP test at an average HR of 180. Now during my ramp test I can’t get over 175…last week at the end of a hard 4h ride (IF 0,8) I did a climb all out, 17 min at 320 Watt and my average heart rate was only 160, max HR 172… Today I rode a small segment outside, 3 mins all out with a max HR of 173. 2 years ago I could go to 189 at that segment (although I rode my best time ever today on that segment).
I would Guess that maybe I’m fatigued but I feel very good and my resting HR has dropped from 55 to 50 over these 3 months.
Could the dropping of max HR be a result of my pure lsd zone 2 training? Or Could something Else be going on? Am I overtraining? The fact that my max HR dropped so much makes me feel like something is not right.
Thanks in advance
