I rode in 2009 (as you will recall, Matt) and 2017, helping out at the Great Easton control in 2013. This year, I'll be at Brampton in a red t-shirt. IMO, while you don't get the en-route support and encouragement that PBP offers, the LEL route is much more challenging and rewarding than PBP and, since Danial, Roger and the crew took over, the organisation and controls are superior.
Sadly, health problems mean that I'm unlikely to ride either again, but it's a great to be involved and to help fellow randonneurs achieve their goals.
