The Voices & Faces of Endurance Planet

Tawnee Prazak, your host of Endurance Planet.

Tawnee Prazak, MS, CSCS, is a triathlete and triathlon coach living in Laguna Beach, Calif., with a huge passion for endurance sports and a master’s-level education in exercise physiology and strength and conditioning. She’s been involved in the endurance world for nearly a decade, and is considered one of today’s leading experts in the field of endurance training, racing, strength training, nutrition and wellness. When not podcasting, Tawnee coaches and consults with triathletes and endurance athletes around the globe. She is also a freelance writer, speaker, fitness model, and healthy cooking aficionado. Find out more at coachtawnee.com.

Athletically, Tawnee is a top-ranked amateur triathlete. She grew up playing sports, including surfing and mountain biking, and began racing triathlon in 2007 while living and going to college in San Diego, the birthplace of triathlon. She had no proper background in swim, bike or run, but she quickly found that she had a knack for endurance sports (and at the time she was also ready to move on from her party lifestyle during her years at SDSU). At her first-ever race — a trail 10k run — she landed on the podium, and a few months later she placed top 10 in her first-ever triathlon. Since then, she has completed more than 60 endurance races ranging from sprint triathlons to Ironman, as well as ultra mountain bike races, road and trail running races, and more. Her favorite distance to race is the half-Ironman triathlon (70.3), and she is a two-time Ironman 70.3 World Championship finisher. With her competitive nature, Tawnee’s run her way to many more podiums and top-10 age-group finishes over the years; she had her first overall triathlon win in 2013 at a local sprint. However, she’s also no stranger to the “bad” days! It’s all those experiences — highs and lows at the races — that help her deeply relate to fellow athletes whether in coaching or on the podcast.

Tawnee documents her training, racing and personal stories (and sometimes posts recipes!) on her blog, www.tritawn.com.

Tim Wagoneer

Tim Wagoneer, AKA “Lucho”, the expert voice of “Ask The Ultrarunner”.

Tim “Lucho” Waggoner, formerly Luchinske, resides in the mountains of Colorado just outside Boulder and is a highly sought-after endurance coach. On Endurance Planet he’s the vastly popular expert and co-host on “Ask the Coaches” (ATC) and “Ask the Ultrarunner” (ATU) shows. His experience in sport as both a professional triathlete and elite ultrarunner brings an incredible wealth of knowledge to the show.

Lucho started running at the age of 10 and went on to multiple Kansas state track and field championships and was a two time All-American in college. He decided to drop out after two years and travel eventually settling in the U.S. Virgin Islands where he lived for four years. Tired of the party lifestyle, he quit smoking and entered his first triathlon and placed third. Fast forward, and four years later he placed 16th overall at the Ironman World Championships in Kona, Hawaii, and was the top amateur.

After 15 Ironmans and beginning a family, Lucho switched to running. He ran 2:41 in his first marathon and then 2:30 in his second. Eventually, Luchoa and his wife moved up to 8,200ft altitude in the mountains, and this led him to try ultrarunning. In his first race, a 50-mile trail race, he won and broke the course record. He then went on to place 6th at the Leadville 100 — his 4th ever ultra. To top it off, Lucho was the overall winner of the Leadman series in 2012, which includes all of the Leadville races. He now spends most his time raising his two sons, coaching athletes, and fishing.

He also has a badass beard, is a sucker for a good IPA, and occasionally blogs at www.joghard.blogspot.com.

Thorsten Radde can be found on our regular “Tri News” show giving the latest triathlon news updates and race predictions (and he is pretty darn good at it, arguably the best in the business). Thorsten, a German age-group triathlete, got started as a “triathlon statistician” out of his fascination for professional Ironman-distance racing. He now regularly collects and analyzes professional Ironman-distance results, allowing him to rate courses and athletes and to predict upcoming races, which can be found at his website trirating.com. He also posts predictions before long-distance races and his analysis of the actual performances on trirating.com, in addition to in-depth analysis and opinion pieces on Ironman racing.

Thorsten brings that expertise to Endurance planet, but if that’s not enough, he offers a few awesome resource for fellow “tri geeks.” He has a free Kona Rating Report at his website that contains tons of data on the participants, a statistical look at how the race may develop. He also authors the “KPR Observer” featuring base information about the Kona Points Ranking (KPR) and ongoing updates during the season how the projected cutoff changes and which athletes are in a good position to qualify. Finally, together with Like Dragstra, Thorsten runs the podcast IM-Predictions.com where you can submit your top picks for upcoming races and maybe win some nice prizes. 

Thorsten was recently featured as one of the “20 Must-Follow Triathlon Accounts” by Triathlete Magazine. You can follow Thorsten at @ThRadde.
