Summer is in full swing and many sports personalities, just like us regular folks, are still enjoying some time off and lying out in the sun, but others are already hard at work, training for future sporting events. This is the case of sprinter Usain Bolt, who is currently training at a Navy camp in Brazil together with the entire Jamaican track team.

The 29-year-old athlete and the rest of his country’s track and field stars have been carrying out their Olympic preparations at the Centro de Educacao Fisica Almirante Adalberto Nunes, a Brazilian Naval training center, with just three days to go until the start of the Games on Friday.

But in between grueling training sessions, the sprinting legend that earned himself the nickname Lightning Bolt took the time to pose for some photos with a group of heavily armed security officers of the Brazilian Navy and post them on Instagram.

Although some of the armed men in the shot appear to be smiling, Bolt captioned the photo “Don’t try test…#BrazilianNavy,” suggesting that these are not men to be messed with.

Luiz Serrano, the naval officer responsible for the training base in Rio de Janeiro, explained that the decision to allow the Jamaican team to train at the camp was largely influenced by Bolt’s popularity in Brazil.

“For us, it’s an excellent experience, to have this very strong team training here because we could see how they train and also for us, it’s a huge pleasure to have Usain Bolt train here,” he declared.

The Brazilian Navy training center features some top-notch sporting facilities that have been made available for use as a training base by athletes before and during the upcoming Games.

The Olympic Games 2016 will kick off on August 5 and Bolt, the fastest man in history, will be competing in the men’s 100 meter, 200 meter and 4x100m relay, seeking to score another trio of sprinting gold medals. The first event he will be participating in – the 100m race – will take place on August 13.
