Lisa Blackburn set a new world record in the 45 to 49 age group at the Ontario Masters Swimming Championships in Toronto last weekend.

She broke the record in the 100 metres freestyle in a time of 58.24 seconds and came within a whisker of setting records in her other five events at the Markham Pan Am Centre.

Blackburn, who also won the 100 and 200 breaststroke, 200 individual medley and 50 freestyle, also tied the 100 individual medley world record in 1:05.61 but was later disqualified.

“I didn’t get all of the records I wanted so I will keep training to get those next time,” said Blackburn, who set a record in the 100IM in the 40 to 44 category at the Rowdy Gaines Classic in Orlando in 2015.

“In my five events I was a total of seven-tenths of a second off breaking all of them.”

Blackburn has made the switch from competing full-time to teaching as a swim coach at Gulliver Preparatory School in Miami. Sharing her knowledge with the children has been a rewarding experience for Blackburn, with the school winning the state championship for both boys and girls in November.

“I’m at the pool quite a bit with my job as the assistant aquatics director, but I’m not able to swim as often as I have in the past,” said Blackburn, who represented Bermuda at the 2014 Commonwealth Games in Glasgow and 2015 Pan Am Games in Toronto.

“I’m finding other ways to keep my training up and I’m in the pool once a day and I’m grateful for that.

She added: “It’s fun and interesting because everyone learns differently and I have to be creative in how I explain things to the children. It’s been a very rewarding experience.”

Blackburn returns to the island next week and plans to host an “Ace Girls Bermuda” coaching clinic at the Aquatics Centre on Saturday, April 15.
