Regan Sikes: Running Through the Elements
I’m Regan Sikes, an ultra runner based in Colorado Springs, but I actually grew up in Georgia and moved here three years ago to pursue my passion for ultra-running. For the last 5 years, running has been a huge part of my life, and over time, I’ve become deeply invested in pushing my limits in the mountains.
I’m one of four daughters, and my entire family is my biggest support system when I race—they love to crew for me, show up at my events, and cheer me on through the highs and lows of ultra distances. Most of my training happens on the trails at Red Rocks Open Space and the Section 16 Trail, where I get a mix of steep climbs, rolling singletrack, and some of the best views in town. I also spend a lot of time running with my two pitties, Murphy and Charlee—they join me on weekday easy runs so they can have some fun (and keep up, at least for a few miles).
Running year-round in Colorado means dealing with every kind of weather imaginable, from scorching heat to snow-packed trails. Over the years, I’ve learned how to adapt my training, layering, and fueling to keep running strong in all conditions. Here’s how I tackle each season:
Winter: Layering Up Without Overheating
Running in cold weather can be a challenge, but I’ve learned that layering smart is key. A breathable, windproof jacket, like those from GOREWEAR, is a must-have when temps drop.
I start with a moisture-managing base layer, add an insulating mid-layer if needed, and finish with a lightweight outer shell that blocks wind without trapping too much heat. The trick is starting a little cold—if I’m too warm at the start, I’ll overheat once I get moving.
I’m always on the hunt for the best performance apparel, and when it comes to cold-weather running, the GOREWEAR R5 Jacket has earned its place as a permanent part of my kit. When winter training in Colorado rolls around, with sub-20°F mornings that make you question your life choices, this jacket is the difference between staying in bed and hitting the trails. Time and time again, it proves itself, keeping me toasty without overheating.
Winter also forces some route adjustments. When the trails are too snowy or icy, I swap them for roads or paved bike paths, where I opt for a road shoe instead of my usual trail shoes. And while it’s easy to forget about hydration in the cold, I make sure I’m still drinking enough, even when I don’t feel thirsty.
Summer: Staying Cool and Fueled
When the Colorado sun is relentless, my biggest focus is hydration and heat management. I start early to beat the worst of the heat and wear lightweight, breathable gear to keep sweat from weighing me down. I also carry more water with me than usual to keep up with the increased sweat loss. Electrolytes become a non-negotiable part of my training. On long runs, I make sure I’m replenishing what I lose to avoid cramping or bonking.
One thing that doesn’t change? My fueling strategy. Regardless of the temperature, I stick to my general rule of at least 65 grams of carbs per hour to keep my energy up. And when the summer heat gets intense, I’ll take my runs to higher elevations, where the cooler mountain air makes long miles a little more manageable.
Spring and Fall: The Wildcards
Spring and fall are the most unpredictable—one day it’s sunny and warm, the next there’s fresh snow on the trails. These seasons are all about being prepared for anything. I carry an extra layer if I’m heading into the mountains, choose versatile gear that works for fluctuating temps, and keep an eye on the forecast to avoid getting caught in a sudden storm. This is also when I focus on building strength and endurance—summer race season is coming, and these months are perfect for hill work and long back-to-back runs.
At the end of the day, running in all conditions comes down to adapting, planning, and having the right gear. Whether it’s adjusting my pace for icy trails, carrying extra water in the heat, or switching between trail and road shoes based on conditions, I love the challenge of running through every season. Some of the best runs happen in the toughest conditions—you just have to be ready for them.
