Jux's 5K Training Week 6
My heart rates have lower than in the past but I think my perceived effort has been more difficult than what I'm used to for those heart rates. I'm not sure what to make of that.
Nice week hopefully you can find a 5k to race in soon. I have experienced what you are describing on HR vs effort as my fitness has improved.
For example I used to avg around 184 in 5Ks, but in my most recent 5K a PR I averaged 175.
10 miler was 180 and most recent 176
Half Marathon was 178 most recent 172
Marathon was 170 most recent 163
The only time I recently I got my heart rate really elevated (184 avg/193 max) was a 5K I ran last July and the misery/suck index was at 160.
So hopefully the increased effort needed to achieve a higher heart rate is a sign that you are getting fitter.
Looking at my old data, I seem to be down about 5 beats on tempos than I was a few years ago. I find our experience interesting because it's not something I've read about. Just guessing here but, for me, I wonder if it's a sign that what's holding me back from being faster is not cardiovascular but muscular. I guess I should start doing strides again (I haven't in a long while) and perhaps shorter intervals.
and hill repeats.
That too. Do you think what I wrote makes sense?
Juxt, it seems to me there are two ways to improve performance. First is to have stronger muscles that demand less fuel (oxygen). Second it to improve the fuel delivery system ..aerobic training. An ideal, then, would be to combine those together. Our long, slow training accomplishes the latter, but we help ourselves, too, by having stronger muscles. And I wouldn't say it's always a case of having stronger muscles ...we just need to avoid subjecting muscles to things they haven't experienced. For example, running a hilly race without simulating those conditions in training takes the muscles into unexplored territory, leading to fatigue and the need for more fuel. I see that as a benefit of sub-marathon pacing during marathon training - when running the race at marathon pace, the muscles feel like it's easy-peasy. (It's why I like marathon training runs of 21-22 miles ..to subject my body to a near-equivalent time on my feet.) Your lower beats per minute reflect your (and
pbm's) improvement. Some strength/speed training could enhance that even further.
I have been trying to recall how much our super-stud,
Steve, trained at and below marathon pace, and what sort of workouts were used. Or, Steve, did the huge mileage you put in accomplish both aspects? Stronger legs, needing less fuel, as well as an improved cardiovascular system?
ETA: It's the point that gruecd likes to stress: Every workout has a purpose. Recovery ...aerobic capacity ...strength ..lactate threshold training.
