Since 2009 I have done a Europe trip each year and only to watch my passion....Moto GP or Superbikes.
2009 Assen, 2010,11,12,13, Le Mans. 2014 short trip to Guernsey, work related. 2015 Assen for Moto GP. 2016 Assen for British Superbikes.
2017 longest trip planned to Catalunya in June 6 days away. Also booked to go Assen again for British Superbikes. Stopping in cheap selfcatering places this year.
Normally 4 days max away for Assen or Le Mans trips.
I travel on my own and meet my brother who lives in Spain and rides to the tracks to meet there. We have used Euro camp sites cos the tents are already set up so cuts down on luggage. It's also best to find cheap B&B near the tracks because the town and track camping areas are mad busy and too noisy.
Travelling alone is fine as you meet some great bikers on the tunnel or ferrys and most times tag along for a good distance to ride as a group. There's always other bikers going the similar routes to you so if you go for the first time you can adjust to riding on the opposite side by following others.
The roads are amazing abroad together with some great scenery and rest stops.
