AA few of many quotes from my conversation with Ian Sharman.

  1. “You go 15 seconds a mile too fast, you go half as far before you blow up.”
  2. “Body awareness is probably the biggest skill you need as an athlete of any type.”
  3. “Being consistently good is better than being heroic every now and then.”
  4. “In a race, it’s your average pace that determines the finish, not your quickest mile split.”
  5. “There wasn’t anything like a secret workout that makes a difference. I just made my easy days easier and my hard days harder”
  6. “If over a six-month period you’ve been able to do about 90% of what you’ve been aiming for, that is excellent.”

Ian Sharman is the author of the new book The Art of Ultrarunning.

P.S. This episode is brought to you by Precision Fuel & Hydration! I’ve been using their energy gels and electrolytes for years, and they’ve become a staple in my race day and long run nutrition strategy. Dialing in your nutrition can make a massive difference in both your performance and enjoyment on race day. I personally aim for 90g of carbs per hour, which works out to three of their gels per hour. Each gel contains 30g of carbs, they’re easy on the stomach, and the flavor is mild enough that you won’t hit that dreaded flavor fatigue deep into a marathon or ultra.
