Not me but I float the option to you of the ferry alternative: Dieppe-Newhaven. Fare from Paris way cheaper and Newhaven may be more direct for you than Calais if cycling on or a straight train to Victoria (shorter than from Dover). I have taken the train both ways Dieppe>Paris (no reservations, plenty of space, avoid rush hour obv, changed Rouen iirc) and also ridden the Avenue Verte south from Dieppe. Ferry takes 4 hours and iirc cost me £32 (bike, one way) last September, rolling up no ticket.
