It's 'Canada against the world' in men's 200m sprint at Botswana Golden Grand Prix

Jerome Blake insists there's no chirping but rather a business-like approach to this week's track showdown with sprint teammates Andre De Grasse, Aaron Brown and Brendon Rodney.

They won world championship gold in the 100-metre relay last summer, but the batons will be tucked away Saturday when they'll be foes for about 20 seconds in the men's 200 metres at the Botswana Golden Grand Prix.

"Canada against the world," Blake declared to CBC Sports via email after arriving in Gaborone just before midnight local time on Tuesday. "We haven't talked about [facing each other]. We all have different things we are focused on.

"I'm sure it will be nice going against each other this early in the season, [maybe] what Canadian [Olympic] trials might look like [in late] July. But my focus is trying to run the best race I can."

Saturday's World Athletics Continental Tour Gold event will be live streamed on CBCSports.ca, the CBC Sports app and CBC Gem beginning at 8:30 a.m. ET, with the men's 200 set for 10:23 a.m. ET.

Rodney is the only Canadian in the race to have competed at the distance this season, having clocked 20.42 for fourth place earlier this month at the Miramar Invitational in Florida. The 31-year-old from Etobicoke, Ont., also posted a 10.17 personal best in the 100 on March 25 in Kingston, Jamaica.

They ran their first 4x100 of the year at the Florida Relays in Gainesville on April 1 in a winning time of 37.80, only 32-100ths of a second off their world performance last July in Eugene, Ore.

"To run [that] fast this early is shocking because we're going to continue to improve," Brown told CBC Sports recently. "None of us felt super sharp. I know Andre's still getting back to 100 per cent [from a foot injury last year], Jerome also dealt with some back [issues] and Brendon seems like he's in better shape.

"It's a matter of us getting sharp and improving in our individual races. [In the relay] we're trying to push our [acceleration and exchange] zone times and improve."

Brown added they could reunite June 9 for the 4x100 at the Meeting de Paris — one of 15 events on the 2023 Diamond League professional track and field calendar — or reconvene at a relay camp before the Aug. 19-27 World Athletics Championships in Budapest, Hungary.

Blake is just happy to be running pain-free. The 27-year-old from Kelowna, B.C., suffered stress reactions in each side of his lower back during a 20.74 effort in the 200 last June 5 in Rabat, Morocco. A stress reaction is like a bone bruise, which arises from trauma or overuse.

After a season-best 20.04 in his opening race at the USATF Golden Games in California and 20.14 clocking at the end of May in Ostrava, Blake noted he "ran in pain" the next two months and never under 20.29, cutting his 2022 campaign short after the 100, 200 and relay at worlds.

"I couldn't run the turn properly [in the 200]. I couldn't start properly because I couldn't push from the blocks with the pain I was in," said Blake, who will use Saturday as a tune-up for the May 5 Diamond League season opener in Doha, Qatar, where he will oppose Brown and De Grasse.
