LONDON — A British TV presenter is trying to cross the Irish sea between Northern Ireland and Scotland in a zorb.

BBC Blue Peter presenter Lindsey Russell has spent hours preparing to run the 34.8 km distance between Donaghadee in Northern Ireland and Portpatrick in Scotland, which will take her 14 very tiring hours to complete.

Russell is taking on the unusual challenge in a contraption named "Bobby" — that looks a little like a hamster wheel — in aid of Sport Relief.

The presenter, who's been dubbed the wave runner, started her journey at 6:30 a.m. just as dawn was breaking in Northern Ireland in the specially constructed zorb.

She caught a beautiful sunrise en route.

And has already faced some tough conditions.

Zorb on!
