Running Events in Colorado

Common Running Events in Colorado - and Various Types of Races!

Races come in a variety of distances and varieties. You can find races based on length or type of running, and each event contains unique sets of rules and challenges. Here are some common types:


  1. Sprints: These are short-distance races typically run on a track, and include distances such as 100 meters, 200 meters, and 400 meters.
  2. Middle Distance: These are somewhat longer track events, and include distances like the 800 meters, 1500 meters, and the mile.
  3. Long Distance: These races can occur both on and off the track, and include distances such as the 5K, 10K, half marathon (13.1 miles), and marathon (26.2 miles).
  4. Ultra Running: These are any races longer than a marathon. They commonly include distances such as 50K, 50 miles, 100K, and 100 miles, but can also be time-based, like 12-hour and 24-hour races.
  5. Relays: These races involve teams of runners who each run a section of the total distance. The most famous of these is perhaps the 4x100 meter relay in track and field, but there are also long distance relays like the Ragnar Relay series.
  6. Trail Running: These races are run on hiking trails, often in the mountains, and can be any distance but are often longer distances.
  7. Obstacle Course Races: These races combine running with various physical challenges, like crawling under barbed wire or climbing over walls. Examples include Tough Mudder and Spartan Race.
  8. Steeplechase: A track event, typically 3000 meters, where runners must negotiate barriers and water jumps.
  9. Fell Running: Also known as hill running or mountain running, these races take place on upland country, with the route often unmarked and requiring navigation skills.
  10. Cross Country: These are typically run on open-air courses, like parks or golf courses, over natural terrain.
  11. Adventure Racing: A combination of two or more disciplines, including orienteering and navigation, cross-country running, mountain biking, paddling, and climbing.

  1. BolderBOULDER: This is a 10k race held annually in Boulder, Colorado on Memorial Day. The race culminates at the University of Colorado's Folsom Field and typically attracts a large number of participants.
  2. Pikes Peak Ascent and Marathon: Held annually in Manitou Springs, this race is a challenge due to its elevation gain. The marathon covers the ascent and then the descent of Pikes Peak, while the ascent race finishes at the summit.
  3. Leadville Trail 100 Run: Known as the "Race Across the Sky," this ultra marathon race is 100 miles long and takes place along trails and dirt roads near Leadville, Colorado.
  4. Colfax Marathon: Denver’s only marathon, the Colfax Marathon is the largest running event in Colorado and includes a marathon, half marathon, and urban 10-miler.
  5. Rock 'n' Roll Denver Half Marathon: This event includes a half marathon and a 10k race. It's part of the Rock 'n' Roll Marathon Series and includes live music along the route.
  6. Georgetown to Idaho Springs Half Marathon: This scenic downhill race starts in the mountain town of Georgetown and ends in Idaho Springs. It's popular for its beauty and the chance to achieve a personal record due to the downhill course.
  7. Run the Rockies: These races in Frisco offer both a half-marathon and 10k option. The route follows the Ten Mile Creek and offers beautiful mountain views.
  8. World Championship Pack Burro Race: This race takes place during "Burro Days" in Fairplay, Colorado. The event is typically held in late July and spans a 29-mile course from Fairplay to the 13,185-foot summit of Mosquito Pass and back. Best part about it? In this race, each runner is partnered with a donkey and they must work as a team. The runner is not allowed to ride the donkey; instead, they can push, pull, drag or carry the donkey.


Side note - I highly recommend the book, Running with Sherman: How to Rescue a Donkey with the Heart of a Hero, written by Christopher McDougall (author of Born to Run). In this book, McDougall details his experience training for, and 

running with Sherman in the World Championship Pack Burro Race.

3 Core Exercises - 3 Planes of Movement
By Emily Kennel September 4, 2023
In the realm of fitness and athletic training, the importance of rest days is undeniable. But the concept of an active rest day — where instead of complete rest, you engage in light activity — has gained traction in recent years as an effective way to expedite recovery, prevent burnout, and maintain momentum. So, how can you make the most of these days to reap all the benefits they offer? 1. Understanding Active Rest Days Before diving into how to optimize active rest days, it’s important to understand what they are. Active rest days differ from total rest days . Instead of complete inactivity, you're encouraged to engage in low-intensity activities that aren't strenuous. The objective is not to push the boundaries but to stay mobile, enhance circulation, and provide mental relaxation. 2. Listen to Your Body The first and most fundamental principle is listening to your body. Everyone's definition of 'light' or 'low-intensity' is subjective. What may be an easy activity for one person might be taxing for another. Thus, while selecting activities for active rest days, choose something that doesn’t exacerbate any pain or fatigue. This could include activities such as light jogging, a long walk, a low-intensity cycling session, etc. If you are interested in finding ways to switch up your active rest days, this article has some good ideas. 3. Diversify Activities To maximize the benefits, engage in activities different from your regular workout regimen. If you're a runner, consider swimming or yoga. This gives specific muscle groups a break while still keeping you active. 4. Incorporate Flexibility and Mobility Work Active rest days are the perfect time to work on flexibility and mobility, which are often sidelined in typical workouts. Activities such as yoga, tai chi, and simple stretching routines can enhance your range of motion, improve postural alignment, and help alleviate muscle tightness. Here are some ways to improve flexibility and mobility, and here is a video that provides a 5-minute daily mobility routine. 5. Engage in Activities that Promote Mental Relaxation The mental aspect of recovery is just as vital as the physical. Engage in activities that promote mental calmness. Walking in nature, practicing meditation, or even doing light gardening can be incredibly therapeutic. This video provides a short mindful meditation sequence to calm the mind. 6. Stay Hydrated and Prioritize Nutrition Nutrition plays a pivotal role in recovery. On active rest days, ensure you're consuming a balanced diet with adequate protein to support muscle repair. Staying hydrated is equally essential, as it aids in muscle function and recovery. 7. Focus on Active Recovery Techniques Apart from low-intensity workouts, consider techniques specifically designed for recovery. This includes foam rolling, which helps in myofascial release, decreasing muscle soreness, and increasing blood flow. Another option is spending time in a sauna or taking contrast showers (alternating between hot and cold water), both of which can accelerate recovery. Unsure how to do this? This video provides a 5-minute foam rolling routine to improve mobility and enhance recovery. 8. Set a Limit While the idea is to remain active, it's crucial to not overdo it. Limit your active rest activities to 20-60 minutes, depending on the intensity and how your body feels. 9. Reconnect with the Joy of Movement Active rest days offer a chance to reconnect with the joy of movement without the pressure of hitting specific targets or pushing boundaries. It's a time to enjoy the process, feel good in your body, and be present in the moment. 10. Reevaluate Regularly As you progress in your fitness journey, your tolerance and capacities change. Regularly assess how you feel post active rest days. If you're more fatigued, it might be a sign to tone down the activity. Conversely, if you feel even more energized, you might be ready to slightly ramp up the intensity. Conclusion Active rest days, when used judiciously, can be a game-changer in enhancing recovery, preventing injuries, and maintaining a balanced relationship with exercise. By listening to your body, diversifying your activities, and focusing on both physical and mental recovery, you can harness the full potential of these days, making your fitness journey more sustainable and enjoyable.
