Run Steep Coaching

Customized Training For Every Athlete

By Giselle Slotboom

Coaching Philosophy

With so many running tips, tricks, and plans available online, it can be challenging finding a strategy that is worthwhile, potentially risking time, money or worse…injury. At RunSteep, my mission is to work with you to develop an optimal training plan that fits your unique lifestyle while pushing you to achieve your biggest goals using the most up-to-date scientific literature. I believe training plans should be fluid and adaptable to life’s external factors, which is why I customize each training plan for my athletes. We work together to make adjustments and track progress while having fun along the way!
