Watch Mark Tewksbury's amazing reaction to Canada's bronze in swimming

The Olympics are an emotional time for everyone: athletes, coaches, parents, fans and Mark Tewksbury.

On Saturday night, the former Canadian swimmer and Olympic gold medallist experienced a wide range of emotions as he watched the final 50 seconds of Canada’s historic bronze-medal performance in the women’s 4x100m freestyle relay at the Rio Olympic Games.

Waiting in the RBC/CBC’s “Someday Space”, Tewksbury was filmed as he watched the final leg of the race, swam by 16-year-old Penny Oleksiak. He begins slightly agitated as he senses the enormity of the situation: “Move over…get away from her,” he instructs the Canadian through the TV, his hand covering his face as he watched.

Then that tension turns to anxiety, as paces back and forth, turning away from the TV broadcast, too nervous, it seems, to watch.

Finally, there’s elation, as he jumps up and down, screaming “Yes!” and “Oh my god. She’s going to do it!” as Oleksiak swims the final few metres. When she finally touches the wall in third place, Tewksbury jumps up again, letting out a mighty “Yes!”

In the end, the team of Sandrine Mainville, Chantal van Landeghem, Taylor Ruck and Oleksiak, finished with a time of three minutes 32.89 seconds to win bronze for Canada.

The medal gave Canada its first of the 2016 Olympic Games and was the first time a Canadian performance earned a medal on day 1 of competition at a Summer Games since 2004.

It’s also the first women’s swimming medal for Canada since Marianne Limpert’s silver in Atlanta in 1996 and the first time Canada medalled in the 4x100m freestyle relay since the 1976 Olympics in Montreal.

It’s clear from his reactions that Tewksbury knew the enormity of the situation, likely because he knows a thing or two about historic performances.

In the 1992 Games in Barcelona, Tewksbury won gold in the 100m backstroke. It was Canada’s first gold of those ’92 Games and continues to be the last gold medal Canada won in swimming at a Summer Games. If Canada were to snap that golden drought during these Games, it's likely safe to say Tewksbury will be jumping up and down with excitement.
