Congrats to our latest members of the World Record Club!

First it was Anne Flower of Colorado Springs winning the USATF 50-mile Championship while setting a new world record in the dazzling time of 5:18:57.

Seven hours later Caitriona Jennings of Dublin Ireland blew away the 100 mile world record with her 12:37:04!
