The pair, Merit Maarits and Anette Parksepp, started their journey today at Taebla in Lääne County, and aim to get it done within three days.

In theory, circumnavigating Estonia without paying a cent ought to be possible, although the four counties which opted out of the free transport scheme, Pärnu, Rapla, Lääne-Viru and Harju, all in the west of the country, are obviously off limits.

Merit and Anette are live blogging the event (in Estonian) here, where interested readers can keep up with their progress.

At press time, the duo had reached Haapsalu.
