A 101-year-old Britain man Buster Martin will be taking part in the London Marathon on April 13, 2008. Once he completed the run, he will be the world’s oldest Marathon runner because the existing world’s oldest marathon runner is 93-year-old.

Buster Martin has been training for the London Marathon and targeting the title as the world’s oldest marathon runner.

He was the former Army physical training instructor. He is also the oldest worker in Britain who worked three days a week at the age of 99.

Before setting new record, he is the world’s oldest person to run the 5K, 10K and the half marathon. He just completed a half marathon in five-hour and 13-minute few weeks ago.
