Around 15,000 runners are expected to participate in the Condura Skyway Marathon 2012: Run for the Mangroves - the Philippines' first-ever midnight marathon - on Feb. 5 beginning and ending at Filinvest in Alabang.

Now on its fifth edition, the game-changing annual footrace raises the bar once more by challenging marathoners to do their stuff in a midnight race that will have them traverse the cities of Muntinlupa, Para-naque, Taguig, Pasay and Makati via the Metro Manila Skyway.

Five other events - 3K, 5K, 10K, 16K, and 21K runs -  will be held in this year's Condura Skyway Marathon, which is committed to support  the group's mangroves reforestation project in Sibugay Bay, Zamboanga.

"We are proud to celebrate our fifth anniversary as we run through five cities in one go with all race categories going up the Skyway for the first time," Ton Concepcion, founder and organizer of the Condura Skyway Marathon said during yesterday's PSA Forum.

One of the most anticipated running events in the country, the Condura Skyway Marathon has distinguished itself as a supporter of efforts to protect and care for the environment. Since 2008, the event has raised over P2 million for projects aimed to protect marine environment, such as Tubbataha Reefs, the whalesharks of Donsol and Dolphins of Bohol.
