PB said:What is better for running fitness ?
I don't seem to be making much progress in my 5K times.
Is it the consistency /frequency ? Is long run base training at slower
speeds better ? Or, sprints for faster miles and 1.5 mile times to increase
lung capacity overall etc... ?
Hard to say without knowing what you're doing. If you're
already running 100 miles per week, then base mileage probably
isn't your problem. If it's 5 miles per week, it could be.
Race times are a different issue than fitness. You can be in
very good general fitness -- pass the aerobic test, good
strength, flexibility, core strength, excellent cholesterol
figures, ... -- and not be in good shape to race a good 5k
time. Racing is more specific about what you are fit _at_.
(Conversely, just because you can run a good 5k time does not
mean that you have good general fitness.)
5k, as mentioned, is a short race (at least to a distance
guy it is), so you want _relatively_ more higher speed stuff
than if you were working on marathoning. But you're still
looking at 80% of your miles being base training, conversational,
miles even in those 100 mile weeks.
If you haven't already built to a base of, say, 25 miles
per week with long runs of 8-10, then you'll drop a lot of time
from your 5k by working almost strictly on your base miles.
And you'll probably continue to do so for the first 2-4 years
of this increased (if it is) mileage base.
For variety, entertainment, staving off boredom, ... it's
not a bad thing -- after you have a running base -- to do
some of your running faster. But you probably have a
while before you need to get fanatic about details on
exactly how fast, long, recovery time and mode, ... Fartlek
is good here -- speed play. Take what will be an easy
4 mile run (in your 25 mile week, 4 miles is a short/easy
day) and, once in the week, do a fartlek. Crank up the
speed for a while (50-200 yards, say), then slow jog,
then regular jog, and then crank it up again. Fun variety,
