On November 1st, 2024, the Donaghadee Chunky Dunkers (DCD) Winter Challenge 2024/25 began: To swim alone, or as a team, a total of 35 km in open water, without a wetsuit or other aids by March 31st, 2025. We never doubted that we could do this!
It turned out to be a challenge, indeed. The first week there was a storm, and we only swam 50 (!) meters at a time. When the weather calmed down, we swam a little longer, but when we swam 435 m in 7 degree celsius water on the 8th of November, it was really nail-biting, and Idun turned somewhat hesitant about whether this was a joyful hobby in the long run.
Research has confirmed that the human body adapts to the stresses of repeated cold swimming, including by converting some fat into so-called brown fat, which can easily be converted into heat when needed. After 3 months of effort, we began to feel that we tolerated the cold better, and now we swim nearly 600 meters without much trouble. But we get shaky! It’s not easy to talk after these swims!
We did it! It turned out to become a rather tough run-in. Knut was unwell for a week, and Idun was in Mumbai the week after (yes, she swam at Yuhu Beach, but fully clothed like they do it there, and DCD runs channel rules: Skin Only, i.e. only a swimming cap, swimsuit/pants and swimming goggles). In a couple of weeks we expect 2 badges to arrive by mail. The entry fee was 10 pounds per person, and we are happy to pay. The profit goes, as mentioned in a previous post, to charity. In total, there were 140 people registered from all over the world for this challenge. Maybe we drew a shorter straw than those who swam in Australia during the same period, but still.
Overall a great challenge, even though we almost gave up along the way. It took a lot of time to fulfill! But we haven’t regretted it, maybe with the exception of that one worst nail-biting swim. And now that we did it – no no, no regrets at all!
