Gareth’s Walk, Bala Lake

The second hike in north west Wales is hosted by 32-year-old binman Gareth. He takes the group to where he lives with his family, next to the beautiful Bala Lake in Snowdonia National Park.

But will his facts and legends - not to mention his strongman competition and smoky sausage - leave him flexing his muscles at the top of the scoreboard? Or will he be tapping out of the competition?
