Today the events team at Chevin sent an Email out to everyone who had signed up as follows:

Regrettably, we write to advise that we are having to cancel the ride on Sunday 14th August due to some unforeseen administrative issues. We’re sure you will be as disappointed as we are on this.
We will be arranging for a full refund of your entry fee shortly – and as a small token of our appreciation of your support, we will also be crediting you with £10 to spend with us in store (to redeem just mention your name when making a purchase at any of our 3 stores).
We hope to re-run the event at some point in the future and hope that you will be able to make it.
Once again, our apologies and thanks for your support.
The Events Team at Chevin

This is indeed a real shame and what a generous gesture crediting entrants. Let’s hope they can re-arrange it again soon – we’ll keep you informed.
