I wasn’t sure when I started this how long this series would be. Previous long series have run to five posts. This will take six. Given his achievement, I think it’s fair to say that Sylvain deserves a six-part series!
As I wrote in the previous post, almost immediately after Sylvain got sick Mike Oram started feeding him, with no discussion with crew. Between getting sick and Mike’s feeding the time lost was about five minutes.
Twenty minutes later was the next scheduled feed, at 16:45, and adhering to the plan wasn’t as important at this time, but Mike again fed Sylvain, this time with a watery porridge, water, and mouthwash to remove the vomit taste. Five minutes after this feed, Sylvain got sick again but reported feeling better afterwards. Less than ten minutes later again, just before 5 p.m. Mike fed Sylvain this time with a cheese spread on bread. We as crew were superfluous at this stage, and since this was Sylvain’s swim and his success the only important thing, it wasn’t about how we felt, so we bit our tongues. From Mike’s point of view about many things in the Channel with his 800 crossings, crew are mostly baggage, which will be not be a surprise to anyone who has read or heard his many ”swimmers are only my third and slowest engine” comments. The 5 p.m. feed was lengthy, taking Sylle over two and a half minutes.
So why did Sylvain get sick? As I’ve also said previously, this happens usually because swimmers take in more carbs than they can process as they mostly are in liquid form and happens many people.
Channel swimming burns about 800 calories per hour. The human body, regardless of size, can take in about 280 calories per hour. Earlier during that morning “discussion“, Mike had ridiculed me for not having a “T-form“, or for not knowing the term. Not needing Mike’s approval I’d asked what he meant, and I had mentioned I’d read all his emails to the Channel Chat group over the years, a repository of which articles Niek Kloots hosts on the Netherlands Channel Challenge site. They are worth reading if you are interested in Channel swimming, and being here, you may be interested, as Mike knows more about the Channel than most people, Fred Mardle and Reg Brickell being the only other pilots with similar experience.
The T-form, is essentially a calorific input/output balance sheet (my explanation). Mike explained to me all about calories and liquids and blood and liver etc, not really accepting that I, or indeed any swimmer, might have some or any knowledge of these matters. Mike explained how he had brought the idea from his sales training in the US, in between his extensive sailing and piloting etc and plotting swim routes from California to the North Channel. Apparently.
Mike’s T-form is the written form of the mental calculation that experienced swimmers do subconsciously or even occasionally consciously. Written down or not, there is the same net result: calories-in do not equal calories-out. Eventually a swimmer goes from having a positive glycogen amount in the liver and muscles to a deficit. Part of training is to get adapted to the transition from glycogen burning to fat burning, also known as ketosis. Writing it down adds nothing except work, unless you are so poorly organised or inexperienced as a crew that your swimmer is feeding too little or too much.
Lisa and Zoe and I continued to discuss with each other and to talk to both Mikes. Mike Oram’s primary assertion was “this year’s Maxim is bad“. He said that this Channel season had seen a significant increase in the number of swimmers getting sick.
Maxim is the most used carbohydrate by Channel swimmers and that used by Freda Streeter to feed swimmers on their Dover Harbour training swims, so it became the default. I’ve used it, Lisa and Zoe used it and many more. Maxim is a 99% maltodextrin carbohydrate and both Evan and I’ve written previously about different aspects of feeding. Evan’s posts on maltodextrin product comparisons and osmolality are particularly useful in this discussion if you want to understand some of the varying factors.
In 2012, Maxim became increasingly more difficult to source until it disappeared. Freda and the beach crew and many others, including myself for MIMS2012, and Lisa, sourced anther product, called Vyomax Maxi. Sylle was using a different product as Maxi wasn’t available in Sweden, but his was still just a generic 99% maltodextrin. I’ve also used Sponsor Competition Sponsor Long Energy, Hammer Perpetuum, Go Energy and others.
During the immediate hour subsequent to Sylle getting sick, Mike Ball looked at Sylle’s feed stuff and then asked why we hadn’t informed him that Sylle wasn’t using Maxim. Lisa and I tried to explain that 99% maltodextrin was 99% maltodextrin, regardless of label, we even still call it Maxim. I don’t think Mike Ball, whom I greatly like and respect, really believed us!
During this time Mike Oram spoke much about noted American Channel Swimmer, friend of his and one of the Channel greats, Marcy MacDonald, who only recently had completed another two-way swim, her third, with Mike, her regular pilot. Mike said she had been sick most of the way, and he’d reverted to the older English Channel feeds of porridge, tea and bread to keep her going.
I am of the opinion, as I’ve written about other swimming subjects, that simple explanations are more likely to be true than complicated ones: Did Diana Nyad catch a magic unknown current and after over 30 hours swimming somehow start swimming faster than world-record pace? Or did she make it all up for money and fame, following a lifetime pattern of attention-seeking? Is all this year’s maltodextrin, regardless of vendor, bad and causing illness, or are more swimmers overfeeding?
It is certainly the case that something had happened that I haven’t yet told you. When mixing the feeds the night before the swim, Sylle had mixed the feeds to quadruple strength, so that when diluted with our warm water supply that was used each feed, the concentration was reduced to double. There was … discussion … of this, shall we say. Lest you think this was a crazy ad-hoc last-minute decision by Sylvain, it wasn’t. Sylvain was already a Channel swimmer. He is a very experienced swimmer, a very experienced open water swimmer, and he was following the feeding regime he always used, including his first Channel swim and which he had used for his long training swims.
During our discussion I mentioned how last year during his English Channel solo, Alan Clack had wanted a double strength feed, and how without telling him, I’d changed it to single strength. In that case I was completely in charge of looking after Alan, and with more experience than Alan, felt sufficiently certain to so do. But I never told Alan, because I knew he needed to believe that I was doing exactly what he wanted.
It’s also the case that I’ve seen a document circulating on email which outlines double-concentrate mixing of feeds. But this document states that this is intended to be mixed to achieve single concentration.
Without actual details of the swimmers affected I can’t categorically say, but in Sylvain’s case, we know for a fact that he was using double-concentrate and that was the cause of his illness, rather than some manufacturing defect.
I use Sylvain to explore further this whole problem and the challenges of gauging individual feed requirements, and situations that can arise, even for an experienced swimmer and crew, and it’s not meant to reflect poorly on Sylvain.
We all make decisions and the Channel finds us all out one way or another.
Keeping the communications open and being receptive to Mike over the next couple of hours, we continued to watch Sylle closely. The tension for us his friends and the concern for him, was high. Over the course of a couple of hours, between four p.m. and 6 p.m. Sylle’s stroke rate dropped from 28, to 26, to 24. Not a cause for panic but needing to be watched.
