Frank Boettcher said:Questions about pace groups, have never done that.
When running a marathon and joining a pace group if there is no group
that matches your target time should you go lower or higher. For
instance, if my target time is 3:50:00 and there is a group for
3:40:00 and a group for 4:00:00, would it be better to go with the
faster pace and potentially fade, or go with the slower group and
strike out a little faster in the last third or so. Anyone have
experience with using a pace group with this situation?
And will a pace group leader normally go out much slower than pace,
ramp up to pace and be negative to the pace at some point in the
second half.
I've led pace groups twice (same race, in 2005 and 2006).
In the example you give here (goal is 3:50, pace groups at 3:40 and
4:00), I would strongly advise that you don't run with either group.
+/- 10 minutes in a marathon is about +/- 23 seconds per mile --
that's a HUGE deviation from a pacing strategy. Might be OK for one
single mile if it was all up or downhill. Don't do it!
Here's what I would do instead, and actually this is just what I did
when I was pacing:
Start with your goal time and whip up a little Excel spreadsheet with
the exact mile splits at each mile marker to produce that goal time.
Then go find all the miles where your elapsed time is close to an
exact minute (plus or minus 5-10 seconds). Round that time to the
nearest minute and consider it to be one of your "checkpoints". I
think in most cases you'll have a checkpoint every 4-6 miles (depends
on how close your goal pace is to xx:00/mi or xx:30/mi).
Now you've got a manageable amount of information to handle during the
race -- your goal pace per mile, plus about 5-6 other checkpoint
times. Keep track of each mile's split, and ease your pace up or down
gradually if you're way off. Then use the checkpoints to see how
close you are to the overall goal every so often. I used a small slip
of paper, but I suppose you could laminate it or write it on plastic.
It's not quite as easy as just following a pacer, and it means you
need to own a watch that records enough splits, but I've found that it
works pretty well. Also, following a plan like this means that you're
actually aiming at a specific time goal, and you can't just hook up
with other runners to have some company. But it's the best way I know
of to squeeze out your best possible performance.
To answer the second part of your query, a good pace group leader
should try to hit as close as possible to dead-even splits between
first 13 and second 13. I also set a "real" target goal of 20-30
seconds under the stated time (just in case), and that's what I used
to work up the checkpoint times. The biggest risk you'll face with a
pace group is getting a yahoo who's never done it before and just
tries to wing it. I think this happens a fair bit, and there's all
kinds of stories floating around about pace groups being 5-10 minutes
ahead of pace. Personally, I wouldn't risk it in a race that I had
trained hard for.
