A mix of cold, rain, and wind is one of the most difficult times to be outside. Trying to run fast in these conditions is even more challenging.
More than 30,000 runners learned this lesson firsthand during the 122nd Boston Marathon, which featured temperatures of around 40 degrees, an inch of soaking rain, and a consistent headwind of 10 to 20 miles per hour.
Like in any race, the results were still largely a function of natural talent, dedicated training, and mental tenacity. But one factor played an outsized role in these exceptional conditions: clothing selection. For many runners, their attire affected their times by minutes and sometimes made the difference between a triumphant finish or a DNF.
I, thankfully, did not race Boston this year, opting instead for the Houston Marathon in January, which had ideal weather and where I PRed in 2:28:24. But I’ve experienced my fair share of crappy race-day weather, including subfreezing temperatures and snow at the Colorado Marathon, cold rain and high winds at 10,000 feet during the Bighorn 100 in Wyoming, slushy rain and wet snow on Col du Bonhumme during Ultra Trail du Mont Blanc, and countless track and cross-country meets as a Bay State high schooler in conditions that mirrored those at Boston.
Over the years, I’ve honed my wet-weather race day kit. Here’s what I’ve learned the hard way.
Dial In Your Prerace Game
Before a race, huddle in a warm, dry spot with as many disposable clothes on as possible. I’m talking multiple layers of Goodwill-worthy clothes that you don’t mind not recovering and a single-use poncho or emergency blanket. A garbage bag works, too. Ditch all or most of these items just before the start or after the first few miles. Having disposable clothes is preferable to using a gear check (if one is offered), because you can hang onto disposable clothes for longer instead of needing to turn over everything 30 or 60 minutes prior to the race.
While waiting to cross the starting mat, avoid becoming deeply cold (feeling like only a hot shower can warm you up) so that it doesn’t take much longer than the standard ten-ish minutes of race pace to warm up. Deep cold is double-trouble: the body does not operate efficiently when it’s cold, and it taps its energy stores simply to stay warm rather than saving them for the race. In addition to wearing extra layers, bring a bottle of hot tea to the starting area.
Know Thy Body
If you were to ask a room of experienced runners, “What’s the best clothing for cold, wet, and windy conditions?,” you probably won’t get a single answer, as demonstrated in this LetsRun thread. Everyone has their own gear preferences, based on gender, body composition, athletic background, seasonal acclimation, personal budget, and more.
As an example, the men’s winner at Boston, Yuki Kawauchi, wore a ball cap, singlet, arm sleeves, glove liners, and split shorts from the gun. But this setup failed professional runner Sage Canaday, who DNFed around mile 18 because he “felt very hypothermic.”
Experimenting with different options in wide-ranging weather conditions is the best way to learn what works for you. The next time you get an unfavorable forecast for an important workout, don’t reschedule. Instead adjust your expectations, get it done, and take notes afterward about what worked and what didn’t.
Understand Fibers and Fabrics
Because personal preference is such large factor in determining what works best for you, the material the product is made out of is far more important than a specific brand or product model. For insulating layers, you really have two options: polyester and wool.
Polyester manages moisture best by wicking water away from the skin and drying quickly. The fibers don’t absorb water. However, water molecules do get trapped between the fibers and so, when wet, polyester is chilly.
Merino wool does not dry as quickly as polyester and it absorbs more water, but it insulates better when wet. Unless you pee on yourself, wool is not warm when wet (trust me), but it is less chilling than polyester.
Waterproof-breathable fabrics like Gore-Tex are a last resort for running in cold and wet conditions. While they are the most water-resistant of the options listed here, they are the least breathable and will be overwhelmed by perspiration if not supplemented by direct venting. The running market is underserved by this category. Most waterproof-breathable shells are made of stiff fabrics and are too heavy and loose-fitting, although there is a growing list of exceptions, like the Ultimate Direction Ultra v2 jacket .
For reasons given earlier, I’m reluctant to provide recommended clothing for cold, wet, and windy conditions, or to list any garments as being the best. There is simply too much personal subjectivity. But I can at least speculate on what I would have worn at Boston this year. Note that I run cold, so many readers may find my choices to be overkill.
Patagonia Capilene Midweight Zip-Neck ($70)
Up top, I would wear a form-fitting midweight polyester top like this one from Patagonia, which would offer a good balance of moisture management and warmth.
Arc’Teryx Norvan Shell ($300)
Over the midweight top, I would need a shell to cut the wind and trap body heat. I have spoken with a few Boston finishers, and most gave a thumbs-up for their wind shell. The women’s winner, Des Linden, wore the Brooks Canopy. If you run cold, it’s even wetter than Boston, or you’re out there for more than just a few hours, a slim-fitting minimalist waterproof-breathable shell like the Arc’Teryx Norvan would be better.
Under Armour Sonic Compression Shorts ($25)
For bottoms, I would wear Under Armour Sonic Compression shorts (full review here), which have a six-inch inseam and are made of 84 percent polyester and 16 percent spandex. Unfortunately, they were discontinued several years ago and I haven’t found a comparable replacement. Short tights would defend my quads against cold precip and wind and cause much less chafing than conventional running shorts. For extra insulation in a critical area, I would wear Jockey Sport Stretch Tech Briefs.
I don’t wear compression socks, but they could help insulate the calf muscles in cold weather. Three-quarter tights that extend below the knee would be a reasonable selection, too. Personally, I would just coat my knees and lower legs with Bonnie’s Balm or a similar wax-based salve.
Naked Running Band ($45)
I use this two-ounce band to stow items not in use, like my shell if it’s not raining or my gloves if my hands are overheating. I wore it during the 121st Boston Marathon, too, but for a different reason: I carried ten ounces of drink mix solution so that I could avoid early aid stations and have a more efficient bottle than spill-prone plastic cups. You can read my full review here.
Headsweats Race Hat ($25)
Showa 281 Gloves ($10)
I bring a Buff on any run in temperatures below 60 degrees or so, mostly to use an earband. For cold and wet conditions, a wool version would be best. Wring it out as needed.
