Coach Giff   Rinnan Coaching

Coaching is both a science and an art. Having a rigorous understanding of the scientific principles/methodologies of endurance training is vital, but so is making sure that each athlete’s training is personally relevant. By taking the time to build a relationship with each athlete and celebrating their successes/failures, a great coach can take all of their knowledge and turn it into a transformational experience. If you are ready to take your training to the next level get in touch with me!


I am a competitive runner, educator and life-long learner. I have spent most of my career making complex scientific concepts understandable and accessible to people of all ages. I have a Master’s degree in secondary science education and have worked as an interpretive ranger, science/math/physical education teacher and as a high school cross country coach.

My first trail race was in 2014 and since then I have set 4 fastest known times (FKTs), won numerous races, improved upon my own high school 5k personal record, completed numerous 100 mile races and was ranked as one of the top 100 ultrarunners by Ultrarunning Magazine in 2016 and 2017. Being a successful runner means being a consistent runner and this applies to new runners and elites alike. It sounds simple, but there is a lot that goes into establishing and maintaining that consistency. Running is just one part of the picture and in order to be consistent a coach must help an athlete learn about how stress management, sleep, nutrition, strength, mobility, running form and mental training all impact their development as an athlete. Start the conversation if you are ready to start working towards your next great achievement.
