Lauren Puretz
Elite ultrarunner
Lauren loves running trail running, short and long, but prefers the ultra distances.
Originally from Michigan, she transitioned to more trail when she moved to Colorado.
Lauren discovered Precision Fuel & Hydration when transitioning to higher carb fueling and joined the team in 2024. She's a moderately salty sweater, so uses PH 1000 electrolytes during training and races, and PH 1500 for preloading.
Away from sport, Lauren is a gynecologic surgeon and mother of two young kids.
Precision Fuel & Hydration have made my race fueling and hydration plans so simple to execute!
