Hello,
Do any of you have done a swim camp in Europe? At like Lanzarote/Tenerife or something like that?
I want to invest a lot in my swimming this winter and thinking about doing something like this. I found a lot of options but would like to hear your experiences!
If you could give me some recommendations this would be very helpful! 
It’s all about finding the right coach and camp.
There are excellent facilities on Lanzarote (Club La Santa has three 50m pools and plenty of swim camps throughout the year), Fuerteventura (Playitas has one 50m pool and quite a few camps but mainly German), Majorca (Best Swim down SE side, 50m pool and plenty of camps there too). Another one to consider is Cyprus as they built a few 50m pools for the Athens Olympics and they’re hardly used from what I’ve heard.
Most camps will be either masters style (lots of lengths, lots of intensity) or triathlete style (lots of video, lots of drills). Each work to an extent but what makes it will be the other people on the camp and how you interact with the coach. You can try to gauge that before you go but I don’t think you can go far wrong as long as the reviews are good, or you post a direct question here once you’ve narrowed in down to 2-3 options.
Best of luck,
SteveMc
