Skinny Tweed Peebles

My son and daughter cycled in this event with their uncle and a friend.  45 miles from Peebles to Biggar and back.  I waited at the top of Dreva Hill to catch them. My son had come up from London and thought he had a reservation for his bike, but discovered that he didn't, and had to leave it at King's Cross and borrow one for the event so he struggled with the unfamiliarity of it somewhat.
Dead impressed with their effort and fitness!
