A woman is currently running across the Irish Sea in a zorb.

Blue Peter presenter Lindsey Russell is hoping to complete the 34.8km run between Donaghadee in Northern Ireland and Portpatrick in Scotland in 14 hours. Russell is taking on the unusual challenge in aid of Sport Relief. The zorb was especially constructed for her challenge which she started at 6.30am this morning. 

Fair play to Russell. We wish her all the best on her challenge. If we're ever to make the trip ourselves though we think we'll take the ferry.
