Each week a member of team talkSPORT will be put through their paces in a different Olympic discipline by former gold medalist Tessa Sanderson and a top coach.
Each of our athletes will also get the chance to replicate Tessa Sanderson's own success. This week it was the turn of sports newsreader Andrew McKenna who swapped his microphone for a javelin - see how he got on by watching the video above.
You'll be able to keep up to date with all the action here with BP Ultimate -- looking after the heart of your car. http://bit.ly/qQopMs
