Planning on running a marathon in a couple months. How should a marathon time compare with the 1/2 marathon split from a half IM?(assume you paced and run well in the 1/2 IM - similar courses/fitness...). Anyone have any advice/thoughts on heart rates for a (planned) 3:20-3:30 marathon. I ran a 1:41 at 1/2 vineman - my biking heart rates were in the low 150's - running heart rates were in the low 150's at the start of the run buiding to low 160's. I paced and ran the 1/2 marathon very well (ran faster than I thought I could run a stand-alone 1/2 marathon). I run 10K's with a heart rates in the low 170's. My run LT is aout 175. I cruise long runs (2 hours) in the 130-140's usually and will build to the low 150's if I feel strong. Thanks.
I've run 2 1/2 IM's both at the end of June in Texas, and I've run 4 marathons all in the months between Oct. and Jan. For me, the marathon is almost exactly double the 1/2 IM run.
I've estimated my LTHR from 172-175 and I always start the marathon at 155 then build to 160-165 by mile 21. After that, it doesn't matter what your watch says, you need to run how you feel.
I have to agree with tom completely on this one. The only difference is that my 1/2IM were in June and July in the northeast, and my marathons were in january and october. My heartrate off the bike was on par with my 1/2 way hr in the marathon (about 160). My starting HR for the marathon is about 155 which is coincedentally identical to tom's. Maybe he is my evil twin brother?
