Get your gilet ready for this early spring ride on the sea wall into a stiffening headwind. Starting at Shingle Street on the Suffolk coast we see several Martello Towers (originally built to defend Napoleonic forces in the 1800s), the second one, Found Tower, being a luxury self-catering retreat looking out over the Suffolk coastline. We get back onto Terra firma at Bawdsey and continue to our finish point at Bawdsey Quay on the mouth of the River Deben.
