Phil M. said:I know it's too early to know for sure, but the October 10 forecast for
Scranton PA (Steamtown Marathon) is "Clouds, cold and rainy, Low 38° F,
High 57° F." If it is actually that cold, then the bulk of my time out
there will be in the low 40s. That isn't too bad in dry conditions, but
once you add rain, things can change.
Looking back on my running log I can see that back in February I've run in
these types of conditions for easy runs as long as 12 miles. However,
racing for 26 miles in rain and cold may be a different story. Anyone have
any tips on what to wear for this?
What did you wear then? Did it work for 12 miles? Would it work for 26.2
miles? You're your own best judge of layers.
Here's my experience and why (probably more than you want to know, but
it includes some data points and I don't believe in messing with
hypothermia). A lot depends on how hard the rain is and how windy. Road
races are going to be more exposed than most traill races (unless above
treeline).
In the 40s without rain, I wear a synthetic t-shirt and my sporthills,
probably xc's in low 40s but possibly voyagers in high 40s, no hat or
gloves/mittens. In your range 38-57, I might lean toward the lighter
weight pants, but I have no experience with them in the rain. I've done
a 2+ hr duathlon with my xc's in a pouring rain in 40s (ugly on the bike
as they got saturated, but I was still warm). I'd probably carry a
light-weight knit hat in a pocket to use if I started getting cold.
With a non-driving, light rain, I use a water-resistant shell. As the
rain intensity picks up or the wind increases, I would be tempted to use
my waterproof shell. It doesn't breathe well, but does have pit zips
which are close to worthless unless it's breezy (too windy and need to
zip them up). For me, warm sweat is much preferable to cold rain and wet
clothes - both from a hypothermia-prevention aspect and probably less
additional weight (unless running in shorts and singlet). Since I'd have
a camelbak on, my back is protected anyway.
My philosophy: Warm legs will be functioning legs. Cold legs are
potentially injury prone. I try to be sure legs are protected then
ventilate through top. Keeping legs warm also helps keep feet warm, at
least in my experience.
FWIW, in Sunday's race, most people looked like they started with one
layer (or maybe a base layer and a very breathable insulating layer)
under a shell and several had peeled to t-shirts by the end. Our
forecast had been for 35-38F temps with wind and rain - and of course,
we already had the 3 inches of slush on the ground. At the race start,
it was only spitting a drop or two. I wore my most breathable shell (not
very breathable in warm weather) that has good wind protection - good
hood, pockets to stash hat and gloves when not needed. I knew it wasn't
waterproof. If I had run the longer race, I would've taken my waterproof
shell and depended on the slight moisture resistance of my insulating
layer to hold off the light mist that was present initially. Having good
rain gear after 2 hrs on the long course would be valuable, esp. if had
to hobble for injury or something.
Caveat: I found 20-40F temps last winter to be about ideal for me. When
it got much above 40, I was slowing down. I've also experienced
hypothermia when I was young, dumb, and ignorant. I go to great lengths
to avoid a re-occurrence esp. since I spend most of my time running (or
doing field work) alone. The ability to make decisions is one of the
first things impaired by hypothermia. I'm especially cautious on trails.
Also keep in mind, that as I was sitting there in the tire change place
for 2.5 hrs, I was watching a pretty hard rain in 20+ mph winds in 38F.
If I had been running the longer race, I would've been running in that.
I know what it's like for field work. So right now, I'm probably
thinking more layers or wind/rain protection than normal.
In other words, what works for you under your race day conditions may
not be what has worked for others. Enjoy.
