I had never swum in the Baltic Sea before, but the name itself conjurs up a cold image, which I needn't have been apprehensive about tbh as the water was generally a perfect 18c! The other bonus was given my preference for fresh water over salt water, the Baltic sea offered a unique experience as it is barely salty at all at 1/5th of normal sea salinity (given >200 rivers enter the Baltic and only narrow Danish straits allow water in from the North Sea). See here to understand more: https://marine.copernicus.eu/access-data/ocean-visualisation-tools/baltic-sea-salinity. We even saw swans swimming in the sea (with their cygnets) and the only jellies were Moon Jellyfish, which don't sting.
The Fehmarner Belt or Beltquerung is the stretch of water which separates the beautiful island of Fehmarn in Germany with the island of Lolland in Denmark. There's not much tide, but it's notoriously windy, which accentuates unique local currents (or Strommungen in German) in the straits and around the islands. We had to reserve our slot for a week on Fehmarn which is no struggle as it's a peaceful place (mainly farming, cycling, wind farms, kite surfing) but if you want more action you'd be bored pretty quickly - luckily we got the swim away early in the week so we could just swan around and chill.
The actual swim route marked by the red line below (if starting in Germany) begins at the beach at Altenteil and finishes around the area of Kramnitse in Lolland. This adds about 3.5km compared to the route taken by the Puttgarten > Rodby ferry (which of course any pilot would be forced to avoid). We clocked the swim at 22.5km.
Ca. 40 people successfully completed (including one 2-way), but zero Brits ratified (to my knowledge) before getting into the water. At the start of 2025, I registered my interest with the Beltquerung admin (Jens Glaesser) here: http://www.beltquerung.de/en.html (they are in the process of upgrading the website to new code thankfully!)
Anyway, a 1:30am alarm clock on Tuesday 12th August for a 3am boat & pilot meet before a 2.5 hour boat ride to the start in the northwest part of the Fehmarn (as we swam Germany > Denmark given whatever wind that was forecast was set to be mainly southerly). The pilot's boat 'Rochen' is slower than any boat I've ever been on and quite exposed so if you do this swim in the rain it would be pretty miserable for your crew tbh!
Shock to the system at dawn-o-clock... a decent 250m swim from the boat to shore at Altenteiler beach just to clear the water to start…boat’s horn marked the off in the breaking dawn gloom.
Another moment where my brain said to myself "what on earth are we doing here?!".
But we were in for a proper treat... after a tough first hour with the entire swim ahead, we were gifted a stunning sunrise (pics below) and an eerily calm sea. It was so calm it looked like it was oil... I have never experienced such calm swimming in the open ocean.
The sun's dawn rays were dancing thru the sea in front of me and certainly helped to mitigate the daunting task ahead with a welcome distraction
My hourly feeds passed broken up by the odd super-tanker clunking past in front of us and we zoomed past the Fehmarnboje (pencil buoy) which meant we were almost 1/2 done.
However, weird local currents had moved us further east and Didi got on the rail with stern look and arms folded telling me to up my effort level to break it (and counting my strokes complaining to Amanda that I wasn't hitting >52 per minute which is tricky when you are 6 ft 3!). I insisted to the crew that I was pushing as hard as I could & gave it everything until the end. (Observe the lucky duck hanging from rope in front of Didi - my lucky mascot on each swim!)
I fed every hour, mainly with cooked new potatoes (very easy to hand to swimmer from boat), alongside heavily diluted squash with maltodextrin. I then switched to flat coke and biscoff cream biscuits for final quarter. These biscoffs were great and ideal for end of swim - we smashed the rest of the packet before we got back to port (along with the remainder of the potatoes and the flat coke)!
Anyway, the finish never came closer but knew the end was in sight with Amanda putting on her cossie then jumping into the water with 1.3km to go….I swam like stink when she got in to leave her behind but she captured the money shot! (Clearing the water on a beach between Kramnitse and Rodby in Denmark)
If you ever want to look like you've done a few rounds with Mike Tyson, then spend 8 hours in the Baltic Sea!
Picked up a beautiful pink granite pebble - a huge mixed feeling of both joy and relief. Back to boat, handshakes with Didi and Kevin then 4 hour slow boat ride back to base in Orth. Long day out for just an 8 hour 14 mins swim!
Special thanks to my firm Berenberg for sponsoring my trunks and hat! Given our company HQ is ca. 2 hours down the road, this was special being the first Brit!
Complete with the Scharz/Rot/Gold-ribboned medal that was presented to me by Did post-swim:
The Crew (with the good ship Rochen in the background): (from left to right) Dieter 'Didi' Lorenzen (pilot), Amanda Bell (crew), Shez, Ursula 'Uschi' Lorenzen (admin), Kevin (local observer). I am fortunate that I studied German at Uni and lived in the country for 4 years so am reasonably proficient. Didi and Ursula don't speak much English and sorting contracts/wiring money/correspondence would have been tougher without that. They are a lovely couple with hearts of solid gold and only wanted me to succeed!
I even made it into various papers in the northern part of Germany and am famous with probs 5 grannies in Luebeck: https://www.bundle.app/en/breaking-news/weitere-beltquerung-brite-schwimmt-durch-die-ostsee-von-fehmarn-nach-danemark-17ED71D2-0FD7-40C7-9B73-83C437FC260F

As ever, over 50% of this achievement is down to the crew. Amanda did all the driving, cooking, organising (you name it) on the trip so all I needed to do was to turn up and deliver. She's one of the finest crew members anyone could wish for so if you fancy this swim in the summer give her a nudge. Pictured with Amanda championing the Yorkshire flag (and before you ask it is the correct way up!)
Didi's boat 'Rochen' is not the fastest but is pretty stable, easy to feed a swimmer from and has a loo (ideal for female crew). However, a solid 2+ hours to the northern part of the island for a Germany > Denmark swim but easily 4 hours + to make the start-line for a Denmark > Germany swim in the event of predominantly northerly winds...
If you ever plan on doing this swim, I would absolutely insist you stay at the sweet little village of Marienleuchte (on the north east of the island) as that has the best jetty to get into and out of the water (I've exaggerated its welcoming with a filter but you can either dive in off the end of the pier or enter in a civilised manner down the ladder!):
This swim is dedicated to my Father, Richard Sheridan, who died on this very day 2 years prior. He ensured the conditions were propitious and pulled me all the way to the finish line.
