Usain Bolt’s age, injury and slight loss in form has casted doubts over his chances for a third consecutive Olympic gold medal in Rio. Challenges from both the world and his own countrymen means the Jamaican may struggle to go out with a last hurrah.

Favourites

Usain Bolt – the two-time Olympic Gold Medallist appears to have regressed in the last couple of years – a recent time of 9.88s is a long way away from both his 2012 (9.63s) and 2008 (9.58s) time. However, we all know Bolt can turn up the heat when he likes and is still currently favourite.

Justin Gaitlin – The 2004 Olympic Gold medallist is set to be the main challenger to Bolt this year – like Bolt, this is also set to be his last Olympics. Strong times last year (9.74s and 9.75s) will be encouraging for the American, who will ensure Bolt cannot be as comfortable as he was in Beijing or London.

Yohan Blake – The Jamaican, now fully fit after his 2014 injury, will be realistically aiming for a spot on the podium this year. Formerly the main challenger to Bolt, it’s inevitable he won’t return to his 9.69s time post injury, but anything below 9.8s will be his aim.

Wildcards:

Andre de Grasse – The young Canadian has progressed year upon year, hitting sub-10s in his last race, but this may be one Olympics too early for him.

Christopher Lemaitre – The Frenchman always appears to be there and there abouts with the 100m, but will need an incredible performance to come close to the podium in Rio.

British involvement:

James Ellington – The favourite of all the Brits (albeit at 60/1), the late bloomer has steadily progressed over the years, and will be hoping to hit a sub 10s race in Rio.

James Dasaolu – Perhaps the runner I’m most impressed with. I feel the 28-year old has a lot of potential for this Olympics and 2020, but again, it will be a decent achievement to reach the final in Rio.

Chijindu Ujah – At the tender age of 22, this is Ujah’s first Olympics, and with sub 10s races already in the bag, it will be interesting to keep an eye on his progress.
