Tyler Heggie is planning on completing a marathon a day for the next seven days while running from one end of P.E.I. to the other.

"For the past about two months I’ve been running about 14 kilometres every day, but yeah, that’s kind of like easy whenever you compare it to this," said the 11-year-old.

Heggie’s run began Thursday morning in Tignish along the Confederation Trail, and he plans to run 40 kilometres a day.

He is doing the run to raise money for multiple sclerosis, in support of his mother Rhoda who was diagnosed with Multiple Sclerosis two years ago.

Heggie’s dad will be with him during the entire run and his grandparents are following along in a golf cart.

"I wanted to do it last year, but my parents were a little concerned that I wasn’t quite ready," he said.

This isn't the first time Heggie has been in the news for his long distance runs.

The P.E.I. Marathon put age restrictions in place after Heggie completed the race at the age of nine. His time was four and a half hours.
