Britain by Bike with Larry & George Lamb
(Channel 5, 8pm-9pm)
In Pembrokeshire, the father-and-son duo head out with a local fisherman to skirt the coast around Little Haven, hauling in pots of lobsters and spider crabs. Heading their separate ways. Larry takes a tour of Castell Henllys, a reconstructed Iron Age fort, while George attempts part of the Tour of Pembrokeshire.
