How To: What Is Afterdrop

Some concepts or acts can be so fundamental to a communal activity that the members of that community can forget that they once may not have known of the concept, let alone the meaning as the activity becomes second nature. These acts, which we might call unconscious assumptions, are not ignored, but accepted, language grows…

Ice Mile Dilemmas – IX – Safety Is Everything

The Average Person? As a responsible extreme cold water swimming promoting organisation, it’s frustrating that the IISA doesn’t seem to appreciate its responsibility in promoting safety and reducing risk. The three-article critique on the IISA rules comprehensively illustrate many of the inherent problems, omissions and contradictions. The concerns of my correspondents and myself with Ice…

Cold Water Acclimatization

This post was a companion to HABITUATION, both of which I wrote in early 2010. Since I revisited and largely rewrote that as Cold Water Habituation, my plan was to do the same in this post also. Acclimatization (acclimatisation for those of us who forego the use of the z)  is a different factor to habituation. While…

The Reverie of Cold

Look away, look away. My head whirls, sentences and clauses. Words and incantations. I need to hold the intent, remember the state. I need to write. I have swum, and now more than anything, I need to write. More than I need people or food, more even than I need heat, I need to vomit out…

Cold water immersion and cold-shock, the first three minutes

I’d hazard a reasonable guess that what puts people off real cold water swimming is not what I write so much about, that is, hypothermia and cold exposure over long periods. Instead I’d postulate that it is the thoughts and fear of the initial cold shock and of the difficulty and pain involved with immersing…

Comments on Diana Nyad’s Heat Drip device

I’m writing this because Diana Nyad asked me on Twitter to comment on her blog, after I’d previously commented on Twitter regarding the unveiling of the Heat Drip device being considered for her Cuba to Florida swim. (To be clear, other than that, I have had no contact with Diana Nyad and don’t know her).…

How To: Prepare for Cold Water Swimming

I’ve touched on part of this before, but thought I’d expand it. Check the Weather forecast. No point getting there and finding out conditions are too bad. Obvious? Yes. Learn from the forecast though to extrapolate to your local spot conditions if you are not close enough to see it. If you are still learning…

Long Duration Exposure Effects of Cold Water

This is quite simple but if you really understand it, it explains a lot of other things. We’ve briefly covered the various stages of hypothermia. For regular cold water swimming, the important thing here is that as temperature decreases blood-flow changes. Blood circulation from the extremities to the core decreases, in order to protect the…

La Jolla Bay and a hypothermia tale

I’ve surfed in San Diego and swam in La Jolla Bay, in San Diego, a couple of times, last time in middle 2008. La Jolla particularly was a great swimming experience for a cold water swimmer like. On friday nights all the local triathletes, including some the of the world’s top professionals, swim from La…

My hypothermia experience…

In 2008 I did the first* Blackrock to Cobh 8 mile (tide-assisted) in October without a wetsuit that took me 3 hours in 12 to 12.5 Deg Celsius. I had already done a couple of similar or longer distance swims but not at this temperature continuously. (I had done Clew Bay at 12 miles and…
