Last time i did it was ~15 years ago, did similar to The Swedish Chef. Ferry over on friday, raced Sat, Sun, then watched the main event, did a load of sight seeing and general riding/training, caught a local mid week race on the wednesday or thursday (got some prize money 😀 ), i did another fairly big race on the Saturday (got my head kicked in, lapped and pulled out after ~30 minutes 🙁 ) then watched a race on sunday (Super prestige i think?). Caught the last ferry home on sunday night. Then home for the christmas hols. Entry fees were fairly cheap IIRC, competition was mental in the bigger events. Good way to spend 500 quid and 5 days holiday.
