Bluebird skies lured a big turnout Saturday to the Alyeska Climbathon, a 10-hour thigh-and-quad killer that produced a new record.
Clint McCool and John Collins both recorded a dozen circuits up and down Mount Alyeska in 10 hours, toppling Collins' old record of 11.
Racers climb the North Face of Alyeska 2,000 feet to the Roundhouse and ride the tram down before repeating the circuit.
"This race is a killer," race director Brad Precosky said in a press release.
Race organizers named the circuits after well-known mountains of about the same vertical distance. Hence, Collins' and McCool's 12 laps totalling 24,000 were dubbed Annapurna after the South American peak.
After 10 hours, all climbing ends. McCool, a regular in the top-10 at Mount Marathon, finished his 12 laps with 25 minutes to spare.
