Empire State Building Run-Up: Hundreds take part in vertical race
More than 700 runners took part in the 38th-annual Empire State Building Run-Up in New York on Wednesday.
The event is part of the Vertical World Circuit, which crowns an overall champion based on rankings points from races such as Tower 42 in London and the Taipei 101 in Taiwan.
Australia's Suzy Walsham won the 1,576-step race to the 86th-floor observatory in 12 minutes and 30 seconds.
The men's race was won by German runner Christian Riedel in 10:16.

Visitors to the Empire State Building can reach the top floor in under a minute by using the elevator.
The world record for running up the building - a climb of 320m - is 9:33 for the men, set by Australian Paul Crake in 2003, and 11:23 for the women, set by Austrian Andrea Mayr in 2006.
Walsham has won six times and holds the record for most victories in the women's invitational race.
The event sees elite competitors followed by the general field of entrants, with staggered start times to avoid congestion in the stairwell.
