But the fastest man on the planet broke cover in his running gear as he sprinted around the Athletes Village in Dalmarnock yesterday afternoon.
The 100m and 200m Olympic gold medallist's home for this week as he prepares for the heats and the final of the 4x100m relay at Hampden Park on Friday, was out in his Jamaica team's black, green and yellow running kit, pounding down a walkway in the sunshine.
Bolt had pledged at a press conference on Saturday that he would be a low key figure at the village.
He said staying in his quarters made him feel more relaxed. He added: "I'll stay in my room most of the time."
Team Scotland runner Eilish McColgan, who is due to compete in the 3000 metres steeplechase at Hampden, was among those impressed after she witnessed him practicing over the 150 metres distance yesterday.
She tweeted: "Watched @usainbolt do some 150s before my own session of 150s. I ended up looking like a sloth on beta-blockers."
Bolt had been piped down the escalator at Glasgow Airport on Saturday, after his arrival on a flight from Jamaica via London, by 18-year-old Colin Flynn.
He told journalists at the weekend that he was looking forward to seeing 'lots of rain maybe and seeing a lot of kilts around the place.'
Bolt added that he was not in the city with any expections of the kind of success he can achieve.
He continued: "I'm just going out and trying to see the country. I guess everybody will try to show me their culture so I know I will see a lot - I will be here for a week and I won't be doing much so I can probably get to move around a lot."
He said he would aim to meet the 'reggae girls,' the name given to his country's Jamaican netball team.
But while the world's fastest man has kept a low-profile, keeping to his pledge of largely staying to the Athletes Village in Dalmarnock, it appears the star's family have been exploring Glasgow.
Cecilia Townley, a teacher from Surrey who is visiting for the Games with sons Frank, 11, and Vincent, 9, got chatting to who she believed were normal Jamaican sports fans on the city's subway, while en route to Hampden Park for tonight's athletics after getting on at Kelvinbridge.
It was only when she spotted the name 'Bolt' on an identity badge that the man she had struck up a conversation with revealed himself to be the sprinter's father, Wellesley.
Also in the Bolt party were his mum, Jennifer, with the family also on their way to Hampden.
Cecilia said: "I looked at his badge and jokingly said 'you're not a relation are you?' He said 'actually, I'm his dad'.
"His mum was there as well with all the family. They were so self-effacing and just really lovely people and so normal, despite their son being one of the most famous people in the world and the man who inspired my children to run.
"They love Glasgow and were full of praise for the friendliness of the people. They were having a great time and it just seemed like a lovely family trip for them.
"For us it was amazing, a great Commonwealth Games moment."
