Time Out says
Grab your best cravat and dust off that harris tweed jacket for it's that time of year again! This tweedy 10-mile charity bicycle jaunt takes in iconic London locations with planned very well-behaved picnic stops and ending with a knees up. A tip from the organisers: bowling hats are more aerodynamic than top hats. Lycra is definitely not allowed.
Please note: The Tweed Run has now sold out, but tickets are still available for the closing ceremony. Visit the Tweed Run website to book.
