Trail Runner Nation

In this episode we speak with Bryce Thatcher, the founder of UltrAspire and a true pioneer in the world of hydration packs.

Bryce has been a runner for over 40 years and has always been fascinated by the intersection of technology and sport. In the early 90s, he noticed a gap in the market for hydration systems that were specifically designed for trail runners. With this in mind, he set out to create the perfect hydration pack that would allow runners to carry everything they needed on their long runs, while still maintaining optimal hydration levels.

Over the years, Bryce's designs have evolved and he has continued to push the boundaries of what is possible in terms of hydration technology. He has introduced innovations like the soft flask, which allows runners to carry their water without the added weight and bulk of traditional water bottles.

Today, Bryce's company, UltrAspire, is a leader in the world of hydration packs and his designs are used by top athletes all over the world. In this episode, we will dive deep into the evolution of the hydration pack and how it has changed the game for trail runners everywhere.

HERE is a video that tells Bryces story very well.

In today's episode, we'll be discussing a topic that is becoming increasingly important for athletes of all levels: continuous glucose monitoring.

For years, endurance athletes have relied on carbohydrates as a primary source of fuel during long runs, races, and training sessions. But what if you could track your glucose levels in real-time to optimize your performance and avoid hitting the dreaded "wall"? That's where continuous glucose monitoring comes in.

By wearing a small device that measures glucose levels in interstitial fluid, endurance athletes can gain valuable insights into their body's response to different types of fuel, exercise intensity, and even stress levels. This information can help you make more informed decisions about your nutrition, training, and recovery, leading to better performance and fewer setbacks.

In this episode, we'll hear from Kara Collier, co-founder and VP of Health and Chief Dietician at Nutrisense, in the field of continuous glucose monitoring and endurance sports, who will share her insights and experiences with this exciting technology. We'll discuss how to interpret glucose data, how to adjust your nutrition and training based on your readings, and how continuous glucose monitoring can help you reach your endurance goals.

In this episode, we're excited to talk about the Petersen Ridge Rumble coming in April in Oregon, a trail race that's not your typical distance. This race, put on by seasoned ultra runner Sean Meissner, challenges runners with unique course lengths of 20 & 40 miles, rather than the standard half marathon, marathon or ultra distances

But why race a non-normal distance? As trail runners, we often seek out new challenges and experiences on the trails. Running a non-normal distance, like the Petersen Ridge Rumble, allows us to step outside of our comfort zones and push ourselves in new ways. These races can also offer a more personalized experience, with a smaller field of runners and a unique course layout.

In this episode, we'll dive into the details of the Petersen Ridge Rumble, exploring the course terrain and the challenges it presents, as well as hearing from Sean Meissner himself about what inspired him to create this non-normal distance race.

Sean is a USATF certified coach and coaches at Sharman Ultra Coaching. Sean has run over 230 ultras and has won at least one ultra every year since beginning.
