I am finding lately that it takes me time to get up to pace... about 2-3 miles.
What do you think about warmingup for a marathon? My thoughts used to be, save energy for the race, but now I am leaning towards maybe a 1 mile warmup at least.

I run a couple of miles before racing, although I'll admit the warmup doesn't get quite as intense as it does before other distances.
What would you gauge your pace was relative to your ability... my warm-up was barely fast enough to actually be running.

Personally, just a few minutes of limbering up and some short strideouts at race pace are all that's needed. Then the first mile or so of the race will get you warmed up. I usually feel a little stiff for the first mile or two, but I don't lose any time.
