As we move into the final events of Olympics 2012, there is a 'Tallented' Aussie the Puntathlete thinks you should consider in the Men's 50km Walk.

Sergey Kirdyapkin won the World Race Walking Cup and his compatriot, Igor Erokhin, was only two seconds behind him.

Australian Jared Tallent placed third in that event, and he is the one I think who will give you the best run for your money at odds. He's double-figure odds (10.5) to win and is in great form according to insiders. 

Have something on him - especially to medal, where he's still in black figures @ Betfair odds of (2.14).

Erick Barrondo is another one to watch at huge odds.

Here's one I am really keen on: Hong Liu from China is my bet of the day.

She's short @ Betfair odds of (3.65), but I think she will just win.

Liu placed fourth in Beijing in 2008, but is really coming into her best form and broke the decade-old Asian record for the 20km walk earlier this year.

The current (1.24) is amazing for Jamaica.

The obvious danger when betting - especially in long odds on - in relay events is a dropped baton. That simply won't happen with the Jamaicans. They're very good at changes and have much more depth than any of their opponents.

This is a race that will go to Dejen Gebremeskel or Mo Farah.

On form, Gebremeskel should win, but Farah could grow another leg thanks to the home crowd support.

I can't split the two of them, so instead offer Bernard Lagat to medal. He'll give you better value than choosing between, or backing both, the two favourites to win. It might be worth having a little nibble on him to win. 

In the unlikely event of an upset, it'll most likely be him.
