Need a little bit of guidance from you all experienced folks. How should 20 minute tempos feel during the workout?
Went out yesterday to run a tempo by feel. Watch was in the pocket so that I would not look at pace or heart rate.
Post workout, realized that I ran faster than what Daniels' or any other calculator prescribes for my race times. Maybe I over-cooked it because I am still sore today. I was also a little bit tired going into the tempo workout so the soreness might be stemming from that also - not really sure.
When you are running the workout, should you be able to extend it to one hour on that same day if there is a need (since tempo are supposed to be run at 1 hour effort)? .
For me, tempos are totally by feel - I usually do them on the track, and try to build up over the first 2-3 laps to just under "that red line" (that's how I think of it) - an effort level where I'm working hard, but not digging deep. I then hold it there until the last 800 or so, when I'll pick it up if I feel good (or maintain if I don't). I usually do 4-5 mile tempos (16-20 laps) so the run itself is between 25 and 33 minutes. When I finish, I like to be happy that I'm done, but I don't want to be exhausted.
Another way to put it is that I'm fine with my tempos being a mental strain but not a physical strain. If I ever feel like I'm straining physically during a tempo, I pull the plug - pushing them too hard reduces the gains from them.
I don't like doing 20 minute tempos just because I do like to feel my way into them, so the first 4-5 minutes may not be quite at tempo effort. (my first 400 is often just slightly faster than marathon pace, and then I ease in). A slightly longer tempo means that I can ease into it, and then still get a good 20 minutes at the right effort level.
When doing a tempo, I never feel like I could extend it to a full hour without it being race effort - my tempos are generally around 10 mile race pace (which for me is a bit over an hour) to half-marathon race pace.
That being said, I do think that it is much better to run your tempo too easy than too hard. So I think you still saw a lot of benefit out of that tempo. And it might be interesting as an experiment to keep your tempos at that level for a few weeks, and see how you progress. You might find that you respond better to that intensity than to a harder tempo.
