An A-road here then, another hundred miles there... did you know there's no eraser capable of rubbing out highlighter pens? I started again, this time using a pencil, some string and three dozen multi-coloured map pins.

We know we're leaving from Blockley early in the morning - if everything goes to plan. That's unlikely but (as lots of you visiting the message board have mentioned 'joining in' might be a giggle), we do need some kind of timetable. In addition to arriving at our planned pit-stops at the end of the day, this also means the Royal Enfield dealers around the country can monitor our progress with fear and trepidation...

Onwards then from Blockley, via Kidderminster to a quick coffee stop at Hitchcocks, and then through Leamington Spa, out towards Wild Wales. From Ross-on-Wye over to Merthyr Tydfill, we should collapse in a heap at the end of the first day somewhere near Swansea, having covered 200 miles. There'll be none of this Ewan MacGregor putting up tents though; us girls are bright enough to know the Travel Inn booking numbers by heart! Or at least, that's the plan.

From a bright start at Johnstown, we'll be wandering up the woolly west of Wales, towards Colwyn Bay for our second night. That doesn't sound very far, but this will be one of the longest legs we're doing completely on our own. Just Us Girls. On The Enfields.

Let's explain: as we come closer to R-Day (Right, we're off!-Day), we'll announce what time in the morning or afternoon we'll be hoving into view at a number of locations around the country. You're welcome to join us for a few miles betwixt Royal Enfield dealerships on those days, and, if we haven't broken the camera by then, we might even ask you to take a couple of pictures for us. Astride our gallant Enfields, munching Jaffacakes, still smiling...

[Smiling? No one said I'd have to smile! My smile is worn out. I need a new one. Maybe I can't go after all. RH]

Now, where were we? Ah yes, Colwyn Bay, boyo. Heading north to Liverpool, we then take a huge detour inland, via Stoke-on-Trent, to spend the night at Coalville. Day Four is the backbone of the country: up through Worksop and Pontefract (making a pleasant change from Jaffa Cakes), whizzing through the countryside to stop at Keighley, just outside Bradford.

If you're in Cowling we might see you early the next morning, before we head off to Preston, Morecambe and Hawes... and that's going to be a really long day, again, on-our-own. There aren't enough Royal Enfield dealers in the Border Counties or Scotland! Not, you understand, that we're hoping for some bright spark in the Orkneys to open a franchise, but the next scheduled stop on the dealer list at the moment is Tranent, just outside Edinburgh. When we keel over in the car-park of whichever hostelry it happens to be in the land of wee haggis, we'll have ridden 250 miles in one day. That may sound like a doddle (particularly if you commute regularly on two wheels), but that's 250 miles, photo-stops at four dealers and not a lot of A-road - so we'll have to hurry if we're hoping to finish that stage before bed-time.

On Day Six, we're high tailing it towards Beverley, in search of a place called Immingham for the night. Then it's Grimsby, Saxilby, Horncastle and Boston all in one day: we should finish near Shipdham in Norfolk, for a pit-stop with the Aged Parents and a good fish and chip supper.

Recharged, we'll then be off into the wilderness of the Fens. From Shipdham it's a quick whizz over to Haywards of Cambridge (they get a special mention up front, because they were Dealer of the Year 2002/2003), and then via Thrapston, on, down to Knebworth. Coincidentally, this devious plan brings us within free-wheeling distance of a certain hostelry in Bedfordshire. A-hem.

From Bedfordshire, we then have what could be the toughest ride of the journey. Out to Southend-on-Sea, then back into London for a marathon around Romford, Walthamstow, Hanwell, Ripley and Horley. Steve the Toast has already suggested I fit a tow-rope to the front of my Electra, attach it to Rowena's bike, and shut my eyes tightly for this part of the journey around London, which could be - shall we say, interesting?

[Trust me, I'm a despatch rider. RH]

After that leg, there's a good chance we'll be meeting up with Daisy somewhere near Maidstone. Then from there, setting out bright and early on Day Ten, we have another of those long on-our-own legs; all the way from Robertsbridge down towards Melplash. With hopefully a curry waiting for us at RC HQ in Bude, it's a gentle jaunt around sunny Cornwall next, taking in Torquay and Bodmin en-route.

If we were to travel as the crow flies on the map, our penultimate stretch would take us to the middle of the Bristol channel. As it stands, the route shimmys up towards Barnstaple, on through Bristol and finally into Swindon for the night.

Finally, Didcot should lead us towards Oxford and out again to Watsonian Squire's headquarters at Blockley, where it all began. There will be a good deal for celebration after 2222 miles.

And there you have it. That's the big plan. It's been suggested that we're barking mad. It's also been suggested that two girls, two Royal Enfields and a large map coloured in highlighter squiggles is a recipe for disaster. Who knows? One thing we are certain of, it's going to be fun.

The ride isn't about raising money for charity: many of you already donate more than amply to worthy causes. It's just about two girls, packing panniers and heading off Round Britain on a couple of classics... and what could possibly go wrong?
