Gilbert Tuhabonye

Founder and Downtown Group Coach

When he started the Gazelles training group in 2002, Gilbert wanted to make a difference. He wanted to help change and enrich the lives of other runners, just as running had changed his own. For 15 years, he has helped hundreds of runners reach their goals – from completing a neighborhood 5K to qualifying for the Boston Marathon.

Gilbert is a natural leader and motivator. Growing up in Burundi, he instinctively took on a coaching role on his high school track team when his coaches were busy with other sports. His genuine enthusiasm for helping others is expressed in every workout as he generously shares his time and talent with each Gazelle. Gilbert and the rest of his coaching staff pledge to create a fun, supportive and healthy environment for runners of all abilities.

Gilbert’s amazing life story is well known across Austin and beyond. To learn more about how his life as a student and top athlete in Burundi turned into a horrifying fight for survival in a national genocide, click here.

Hannah Lewis


Hannah started running with Gilbert’s Gazelles in 2009. A novice runner, with two toddlers at home and working full time as an engineer, Hannah set her sights on improving her fitness and running a “fast” 10K. After a few weeks of Gilbert’s coaching and the contagious energy of the Gazelles, she moved on to a bigger goal – running a marathon. Gilbert’s coaching took her from being a beginner 5K/10K runner to a Boston marathoner. Eight years and 14 marathons later, she has taken nearly an hour off her original marathon time.

In February 2015, Hannah's passion for running and love of the Gazelle family led her to a permanent role with Gilbert’s Gazelles as business manager. Her marathon success is secondary to the joy of running with friends and the camaraderie of the Gazelles. Hannah still loves being a part of this great Gazelle family!

Sonya Manson

Far West Group Coach

Sonya's running background started out in high school, running cross country, track and the Capital 10k. However, she didn't catch the running bug until after teaching fitness classes while in college. Sonya started teaching various fitness classes at World Gym, Gold's and some corporate fitness programs in Austin while going to school. She ran for a change from the gym scene and found she enjoyed it more.

Sonya first coached a marathon group for Austin Fit in 1996 and ran her first marathon and qualified for Boston. Since that first marathon, Sonya was hooked and has run 14 marathons, including Austin, Big Bend and New York. She also loves 5K's, half marathons and triathlons.

Kenny Hill

Assistant Coach

Kenny Hill started running at the age of 46 as a way to get in shape to play soccer with a coed team. His first goal was to run four laps nonstop at the local track. Kenny soon found he was a better runner than soccer player and started entering 5K and 10K races. Encouraged by his early race results, Kenny started training with RunTex University and later with Mixon Henry. Kenny was drawn to the marathon after running the anchor leg of the five-man relay at the Austin Marathon. He then trained with Austin Fit and ran his first marathon in 2000. Since then he has run 12 marathons, four of them at Boston. 

Kenny joined Gilbert's Gazelles in 2003. Over the years, he has matured with the sport and earned an assistant coaching position under Gilbert.
