Age has proved no issue for Canada's Brian McKeever, who claimed a record-equalling 16th men's Winter Paralympic gold medal at his final Games.

Para cross country skier McKeever and sighted guide Graham Nishikawa triumphed in Saturday's men's sprint free technique vision impaired, after previously snagging gold in the middle distance free technique and long distance classic technique.

In the process, 42-year-old McKeever drew level with para alpine skiing legend Gerd Schoenfelder's record of 16 men's gold medals.

"It was because they gave me the right bib today," McKeever joked after wearing bib No.16 for his 16th gold.

"We talked a lot about pacing - pacing at altitude is the most important thing. If you blow up at altitude, you're not coming back.

"We just nailed it right off the start. You could just see it; it was the right pace."

McKeever, whose brother Robin was his sighted guide earlier in his career, won three gold medals in PyeongChang, Sochi and Vancouver plus two in Turin and Salt Lake City.

His cross country career also delivered two silver and one bronze medal, while McKeever claimed a biathlon bronze medal in Turin.

He was named in both Canada's Olympic and Paralympic squads in Vancouver 2010 but ultimately didn't make his Olympic debut.

McKeever, who announced pre-Games he was retiring, isn't changing his mind.

"We're breaking down. We still love getting out together but it's getting harder," he said.

"I think if we end up back here trying to race in four years, we'll be coming in on canes."

Next comes a final swansong and McKeever's attempt at gold No.17 in Sunday's relay.

"After 20 years of doing this, it's an honour to be a part of the Paralympics," McKeever said.

"So we'll go out and enjoy it and still make ourselves heard, keep on going and enjoying this beautiful weather we've had and looking forward to finishing on a fun day."
