Here's the deal: for every donation that you make you can have a guess as to the time that it will take us to get from the start line in Goodwood to the finish line in Ulaanbaatar. Be as specific as you like and guess either a total duration of days, hours, minutes and seconds or a date and time when you think we will finish. Duplicate times will be disregarded.

Remember to leave you guess(es) in your comment when you donate!

To give you a better chance at estimating: we will be starting at Goodwood, West Sussex at approximately 4pm on Saturday 23 July. We will be travelling in a car that is no older than 10 years and has an engine of less than 1.3 litres, something like a Nissan Micra or VW Polo, possibly a Toyota Rav4 or one of those little Suzukis (if you have a spare one of these or similar hanging around, let us know). There's just one Czech point (haha) which we leave (I think) on July 25 and then the route is up to us. We plan to go south of the Caspian and Black seas, ie, via Turkey and Iran. We also plan to stop off in Odessa.

Using straight lines this is 6,273 miles. Using Google directions it's 6,723 miles to Korday, Kazakhstan where it stops giving directions. When making our visa application we estimated that it would take us 5 weeks. Last year roughly 2/3 of cars made it to the finish line. Feel free to do more research on the Rally.
