Another great guest for Paralympian Dan Greaves and Olympian Martyn Rooney.  This time it's 6 times Paralympic gold medal winner and 8 times London marathon winner Dave Weir. Dave tells the guys he's in the best shape he's been for a long time and first the first time in ages he's really enjoying the sport again.  He talks honestly and openly about the mental challenges and depression he's faced, especially in recent years, and the counselling that he's had to get him back to this point.
