					thanks kf! and yes, i think i'm on this aerobic train for the foreseeable future. might return to strength and power focus at some point down the line - for long term health, it's probably a good idea - but at the moment i'm enjoying this journey.
- run 46:59, 8.68 km
i found myself back in the original sirpoc norwegian singles approach thread yesterday and then down the NSA rabbit hole. kept this very easy/slow partially as a result. that is, i always meant this to be an easy run but found myself trying for the first time in a while to keep HR under 130. perfect conditions, high 40s/~9C and no wind. 
sirpoc has, as he admits, the advantage of living somewhere very flat. that makes sticking to a prescribed pace much easier. today, HR crept over 130 a few times on climbs even as i slowed down, although average was 127, which is spot on. as i'm thinking about doing something like his marathon build - weighing it against doing a jack daniels-type or pfitzinger-type build - that's one of the sticking points for me. it's not mountainous where i live, obviously, but it's not all that flat, either. there are decent flat loops i could drive to, but that's really only practical on the weekend. something to think about: where are the flattest practical loops - minimal or ideally no road crossings, within 3 km on foot - near me.
