Hello and happy new year! I need a bit of advice on Hadd's heart rate training if anyone can help. I've been doing base training for some weeks now but only just got round to reading 'the' Hadd article all the way through, and want to clarify a few things if that's ok, would be a great help.
1. What Hadd calls HRmarathon, calculated from my actual max HR, is 184 (204 max minus 20 bpm), and according to Hadd my easy running HR should then be 30 bpm less than this, or <154. But in the article he also says that if your HRmax is 193+ (even if over 200, which mine is), then you should do your easy running at <145, and start initial lactate threshold heart rate (LTHR) runs at 155-160.
I'm now a bit confused which of these I should be following. I have been working to running at <145 anyway (based on 204 x 0.7), but then according to Hadd's general guidelines for all max HRs over 193, the initial LTHR runs at 155-160 would be my 'actual' easy run pace, according to my actual HRmax.
2. When doing Hadd's test of repetitions of 2400m, given my HRmarathon, I presume I should be doing 5 repetitons for the following HRs: 150, 160, 170, 180 and 190 -is this correct?
3. A bit of background. After completing my first marathon in October last year I've been doing base training for 6 weeks now, getting down to <145, running 5/6 days per week (4/5 x 6 mile runs in the week, Saturday off and a 10 mile run on Sundays). What I want to know is how should I incorporate LTHR runs into my existing schedule, and the more specific training I will be starting soon? I have a half marathon on 25 March where I hope to do 2 hrs or just under (PB 2:10), and my second marathon on 27th May where I'm aiming for 4:30 or just under (PB 4:39).
I was planning on following Shades level 2 marathon plan (18 weeks, 4 or 5 runs per week including 1 or 2 speed - mostly tempo - sessions), but I see that Hadd doesn't adivise tempo runs until you can do 10 miles at HRmarathon without loss of pace, and I don't think I have sufficient time to build slowly to this before the half and marathon training would begin. I'm therefore wondering how best to continue with Hadd's principles whilst training for my half in March and full marathon in May, given my goals for both races and the time available.
Although I've yet to do any specific tests to measure my progress with base training over these past weeks I'm sure I'm seeing some improvement and want to carry on following the principles, and I've been told that Hadd's give the best results.
Sorry this has been a really long post and thanks for any views.
