HR Zones and Running
Long time lurker and drawing a blank. I've got a couple of sprint triathlons under my belt and am moving up to longer with a goal of hitting IM next year late in the season. With that said I'm a long way off, I've read everything I can absorb and Don Fink's Ironfit seems to strike a chord with me so I'm trying that.
My issue is the timed zone training. I can bike and swim easily enough (easily being subjective) and can maintain the zones needed but on the run...I just can't.
I'm not a big runner, I've never been able to run for long periods, but even going slow I seem to settle at about 3.9-4.3 no matter how slow I go. Is it just a 'comes with time thing' or should I get a coach to look at my gait etc and see if I'm really inefficient? I'm only doing a few miles at the moment, but it just feels like a bit of a stumbling block. If I can't get the effort levels down then it will be a long haul! Ether way I'll do it, but just wanted some running advice!
