Working with Jon Kuanfung, RD has been the key to successfully completing my first marathon at age 63! I began training with Jon at a baseline of 3 miles, 4 months prior to race day. Jon's methodical problem-solving skills over every obstacle and constant encouragement made my goals achievable each step of the way and we have been on a journey! When I was at a standstill during training, Jon's compassionate listening and attention to detail got me back on track as he adjusted my nutrition intake and recommended targeted muscle strengthening. Jon's knowledge of nutrition, proper fueling and hydration for my body's sustenance and recovery from the flu twice during the training period prepared me well within the time frame of the marathon. I am most proud of completing a strong marathon, never hitting the wall, running consistent splits injury free, and fully recovering within 48 hours. Because of the expert advice of Jon Kuanfung, RD, I achieved my goals, had a great experience and even placed first in my age category!
