I'm a new recruit to the Hadd cause. Been running since Feb 2009 and recently completed marathon No. 4 in Frankfurt for a new PB of 4hrs 12min, an improvement of almost 17mins on Mittelrhein back in May. I've taken a grand total of 36mins off my first marathon time, Stratford in Apr 10. I've managed 2 44min 10Ks and a sub 1.45 HM, all this year off a Hal Higdon intermediate plan for the first half of the year which I felt gave me a reasonable base. I followed a RW Garmin plan for Frankfurt which I felt really good with, the variety helped a lot.
So I started Hadd last week, aiming for sub 140HR, it's a level I find easy and fits well as I'm still in recovery phase from Frankfurt. Next week I shall do a MaxHR test and the following week a 2400m Hadd test, which will hopefully give me the right info to work off. If all goes well, this winter will give me a better base as I'm starting earlier, 2 main races for 2012, Dusseldorf marathon in Apr and Cologne marathon in Oct.
Only problem I'm finding at this time of year is it can take a while for the HRM to settle down, I put it down to the cold snap at the moment drying out the contacts. This morning's run, I was averaging 239 and 198bpm for the first 2 miles and 222bpm for the last. Otherwise it was 132-137bpm for the 5 miles inbetween when I upped the pace a bit.
There endth the life story
