American distance runner Abbey D'Agostino got tied up with New Zealand athlete Nikki Hamblin. After the fall, D'Agostino waited to make sure Hamblin was ok and both finished the race. D'Agostino finished despite collapsing to the track with an apparent knee injury. This is the sort of performance and sportsmanship that seems destined to be regarded as "Priceless" in Mastercard commercials for decades to come. UPDATE: D'Agostino has protested and gained entry into the women's 5000m final Friday afternoon.
