Separate crashes that seriously injured two cyclists have snarled a 100-mile (161-kilometer) amateur bicycle race from London into the Surrey countryside. Emergency services say one man crashed into a tree, while the other fell from his bicycle and suffered serious head injuries. Among thousands taking part Sunday in other RideLondon races were reigning Tour de France champion Chris Froome and retired middle-distance track star Kelly Holmes, who won two gold medals for Britain at the 2004 Athens Olympics. Many racers say they were delayed for close to an hour as organizers of the fund-raising event opened up a longer alternative route. Air ambulances carried away two of Sunday's participants in the RideLondon-Surrey 100, which is part of a three-day cycling festival organized annually following London's hosting of the 2012 Olympics.
