During the BOLDERBoulder Professional Team Challenge last week, Patrick Kiprop and Jesca Chelangat were the first athletes to hit the Folsom turn just beyond the 2 km mark, each earning the $1,000 First to Folsom Prime bonus.
A huge thank you to FirstBank, now a part of PNC, for supporting this exciting race feature, adding even more intensity and excitement to one of the most competitive moments of the day!
Today, we celebrate everyone across the world who has made the BOLDERBoulder so special. This year, people from 26 countries and all 50 states came to Colorado to celebrate health, fitness, and the running community.
Boulder showed up in a big way once again. From the packed cheer zones and live music to the costumes, cowbells, high-fives, and unforgettable finish line moments, the spirit of the BOLDERBoulder was everywhere. 🏃♂️🏃♀️⛰️
Thank you to everyone who came out to run, volunteer, cheer, celebrate, and make Memorial Day in Boulder unlike anything else.
And a special thank you to WK Real Estate for their continued support of the BOLDERBoulder community.
