Hadd Is Doing The Rounds Again

Posted by plu , 14 July 2007 · 118 views

Hi all,


I note that Hadd is doing the rounds again amongst some bloggers started by this post by Ewen. It reminds me I am one year older and should adjust my heartrate training zones. My maximum heart rate is somewhere between 174-179 and in the HAdd article this is the relevant section for me:

Quote

If your HRmax is 173, read all of the above, but use the following numbers:

Best possible HRmarathon: 155-157 HRav

Easy running: 125 HR or lower (This training HR will not change with time - it may drop, but the pace at this HR will definitely improve.)

ILTHR: Begin with 135-140 and only move it up (only by 5bpm each time) when your pace vs HR is steady and you are able to run 10 miles at the particular HR without loss of pace or rise in HR. You are eventually trying to reach a state (some weeks or months down the line) in which you can run 10 miles at HRmarathon with no rise in HR and finish confident that you could go round again at the same pace with no rise in HR or loss in pace at constant HR.


Here are my statistics:

Age 47 yrs

Resting Heart Rate (RHR) 60 bpm

Maximum Heart Rate (MHR) 177.05 bpm

Working Heart Rate (WHR) 117.05 bpm


Training Zones Heart Rate Objectives
60% 130.2 Fat burning and re-energise glycogen stores
70% 141.9 Develop oxygen transportation systems
80% 153.6 Improve lactic acid threshold
85% 159.5 Lactic thresehold
90% 165.3 Speed


All very reasonable and I know it works but my body has to let me run the distances required.

cheers Plu




Hi Martin, what's with the extra 0.05bpm? As you know, I'm trying John Hadd's program to see what happens. I'm curious.

The thing that worries me a bit is the mileage - his famous pupil ended up running 160+km per week. I'd be hoping to see some results off 100km, which is still pretty big, as I'm averaging 60-70 km this year. I'll let you know how it goes in a couple of months.

By the way, my MHR is 166 (from testing), RHR 52 (lying down). Age is 50 :)
