What follows is what happens when you give a New Jersey-based Texan your Twitter account for the day....
HELLO!!!! @jgalswims here! our swimmer is looking stunning today! Weather fab - layering the sunscreen right now.
We have said our goodbyes and are now on board this utter beaut of a boat!
Boat captain John from Staten Island shows Patti the technology on board. We are covered on all our charging needs.
Apparently this is our new swimmer! Bit of a conundrum here at Pier 25.
Right, we are en route to the start, running 15 minutes behind schedule. Such is the life of marathon swimming.
Just hit the starting line. It's real now! Swimmers are en route.
In other news, this is New Jersey, where I live. The skyline is not quite as spectacular, but our bagels trump NYC.
The Staten Island ferry just honked at us in a serious way to move. We high-tailed it to get ahead!
She's off. #NYC #MIMS2013
Connecting with Karen now. Sun is fabulous now. Jackets off, short sleeves from now on! #MIMS
For those of you just tuning in, this is @jgalswims tweeting for Karen who is SWIMMING AROUND MANHATTAN right now. @nycswim #MIMS
So finding your swimmer is quite the feat. But in the meantime, this is the Brooklyn Bridge. They flew through it.
We found them. All is well. Heading to Williamsburg Bridge. #MIMS
FYI folks: not sure if it's tracking by boat, but #7 Karen & #15 Jim Neitz are on the boat Fransea.
As in, our escort boat is Fransea. they're not on board! They're swimming like pros.
FYI I want Karen to get out and see a whole slew of followers so RT and Follow if you LOVE New York! :D
Heading up the East River I think. But what do I know, I'm a Texan in Yankee territory. #yeehaw #sorryImTexan #MIMS
Hey @NYC did you know swimmers are circling your island right now? How cool is that. @nycswim #MIMS
I present to you, #drumroll, MIDTOWN. #NYC #MIMS
First feed going in and swimmers report smiles on their faces and sunshine in their hearts. That's what #NYC does to you, people.
Oh, I forgot to show you the whole reason we're here. Hello, Karen! Right behind the red kayak.
I am your resident token Yank today, Britain, but I wore my cat shirt in honour of Oscar. Note: Spelling of honour.
Karen has passed the Empire State Building en route to the UN. They tell me this is where all the foreigners are.
Hard to get a good pic, but here's the hero of the day! #MIMS #NYC
FYI, here's where she is on a map. Pretty cool, huh? @nycswim
World, this is Long Island.
I've gone for a feed. Jelly babies have nothing on Swedish Fish. Y'all don't even know.
Karen is heading into posh waters as we near the 69th Street Bridge. We should feed her a champagne mojito. #MIMS
Our technical side of the crew @pattiswim reports 63 stroke count. I have no idea what that means, but data is good in this day and age.
Beautiful swimming by our beautiful swimmer. She has just passed the 69th Street Bridge.
A sky tram ferries people to and from Roosevelt Island. This is why USA rules the world, people. Except Texas. #MIMS
Our heroic swimmer doing something very big today. GO KAREN!!! #MIMS
I've moved to the sky lounge. Here's our other crew @pattiswim doing a fantastic job keeping Karen fed. Vital! #MIMS
Making a move to up the speed for Hellsgate. Once she passes that, she's going to get a nice push from the current. #MIMS
She's with the red kayak. She has less than a mile to go before we enter the Harlem River, aka lunch time! #MIMS
Fighting like a CHAMPION. She's in the toughest part of the swim. We need your love - now!!!
She's drawn a crowd and we're cheering like mad. About 20 mins of fighting to go. NEED LOVE FOR HERO!!! #MIMS
GO KAREN. OMG she's so close.
Tide turned. Karen on the boat and okay.
Karen: "I'm in it for the glamour";)
She's back in. they will get the designation "boat assisted swim".
This is where Karen has re-started her swim. #MIMS
Finally close enough to get a swim shot!
If only Karen could see the billboard she just passed...Let's just focus on our powerful swimmer!
Karen happily pacing along :)
Karen trucking along the Harlem River. She has an amazingly consistent stroke!
In other news, I just had lunch, and am now contemplating lunch 2. Or maybe a post-lunch snack. Either way, I'm ready to eat.
Our Karen is feeding and switched goggles. She has abandoned blue for yellow. Fun times in the river. #MIMS
Flat calm and rather warm out. That's an example of me trying to talk like Karen. The Texan version: NICE'N HOT OUT Y'ALLLLL.
It's like she's doing a nature swim in a lough somewhere... This is Manhattan?
She's well into the Hudson River now. Tappenzee Bridge ahead. #MIMS
Karen may know her geography as a Brit, but this here Tex can't tell a continent from a train line. Apologies. That's the GWB.
In other news, New Jersey is stunning. Karen is well impressed with my new home state. Even though Texas is better.
Karen approaching the GWB, 6 hours, and BLACK JELLY BABIES TIME. Her favourite. (An Oxford comma for her alma mater).
The George Washington Bridge is really cool when you don't have to pay a toll. #MIMS
The co-boat captain brought on a big bar of dark chocolate with almonds. She didn't know I was on her boat. Chocolate gone now. Sad face.
I says to her, in my faux NY accent," if you offa, I'm gohna take it". Rookie mistake with Channel swimmers on board.
Karen swimming majestically in front of, wait a minute, New Jersey! I should work for the tourism board.
The other crew Patti (who's clearly much more responsible that yours truly) tells us we are here. Literally.
Conditions toughening as tide changes, but Karen is swimming along fine and strong. #MIMS
Oh look! It's Karen! Approaching 7 hours and feeding now.
Look. A British Airways plane for Karen!
Oh look. It's Karen making good progress! #MIMS
Karen all smiles. Truly happy. She waved at me!! #MIMS
Karen is in the village. I put on my skinny jeans and hipster black glasses to let her know.
Final push. She's tired but no complaints whatsoever from our Karen. Hero.
It's Karen and she's DONE!!! #MIMS
Swimmer safe on board and delighted with herself! Let's get some congrats love to our Karen ! #Hero #MIMS
Karen is off enjoying a recovery massage. And I'm sad because I have to go back to being plain ole @jgalswims now. #MIMS
The team is back and Karen is fab! I've thrown in heaps of American symbolism for you as a parting shot. #MIMS
Thanks, too to her and Patti for crewing, John (boat pilot), Bill (observer), Jeff (kayaker) and all of the volunteers and friends who made the day so memorable. Many thanks also to all the people who sent texts and tweets throughout the day, and who have been in touch since. Not the day we'd hoped for, but quite a day nevertheless.
