With oral antibiotics and painkillers not improving Griggs’ situation, a decision was taken just over two weeks ago that he would be admitted to Musgrave Park Hospital.

“Thankfully, the intravenous antibiotics have finally led to an improvement and Nick was able to sit on an exercise bike for a couple of 20 to 25-minute cycles this week, which was the first exercise he had done in six weeks,” said Kirk.

Griggs’ outstanding form last summer when he clocked huge 3,000m and 5,000m personal bests and also bettered his 1500m time, led to him earning spots at the two premier US indoor meetings, the New Balance Games and the Millrose Games, but getting well again has become his current priority.

“Nick is making good progress now, but he’s going to have to continue getting oral antibiotics for another four weeks so we’re just going to have to see how things go,” Kirk said.

“Joining our group of athletes for a training camp in the French Pyrenees in April is probably a target for him, but we’re just going to have to see how it pans out.”
