Sean is incredibly knowledgeable on all things running and fitness. Sean coached me for 8 months and brought my 5K down more than 90 seconds and took 40 minutes off my marathon PR to break 3 hours! He was very flexible on scheduling and thoughtfully answered countless questions on training theory, mechanics, run strategy, and diet. Sean had a great ability to gauge the fine line between tolerance for mileage build and avoiding injury. He strategically pushed me out of my monotonous training routine with a mix of speed work necessary to attain the level of physical and mental ability required to hit my goals. Perhaps most importantly, he is a very down to earth person who genuinely wants to see you succeed. I highly recommend working with Sean!
