11-mile swim - Post Event Analysis
Firstly I want to say a huge thank you to this forum for all the advice and support offered. On Sunday I completed my final goal for 2018 by completing an 11 mile swim in 5 hours 45 minutes which I’m very happy with (for those that are uber swimmers: the winning time was 3 hours 58 minutes).
I’m writing this thread to say thank you but also because a lot happened during that swim that I’ve never experienced before and would like to get your views. The night before the swim I ate a large 3 course meal (this could well have been my downfall – see later). As to the swim itself I noticed the cold almost immediately! I’ve done plenty of lake swimming over the summer but I’d never felt the cold before (temp was 16 degrees or 60 fahrenheit) which slightly concerned me. I also felt really full right from the off. I’d agreed with my kayaker to take my first feed on 50 minutes and thereafter every 30 minutes (alternating between just water and water/gel/oat bite) which is the plan I’d trained with and never had any issues with. By the 2 hour mark I really didn’t want water or food but I tried to get something down and stick to the plan. From the 2 hour 30 mark I opted to avoid the feeds because I really couldn’t stomach the idea of taking anything. Then the inevitable happened at around the 3 hour 30 mark and I was really ill – this is the first time it has happened and had no idea where it came from. From that point on whenever I stopped I was ill every time. The only other factors which may be relevant was that the water was slightly choppy at times (but nothing awful) and I felt worse when I held on to the kayak during the feeds (this wasn’t a swim under strict channel rules).
So does anyone know what may have caused my illness? I am thinking its overeating the night before on account of me feeling full at the start of the swim but I’m not sure if the cold, forcing myself to stick to the feed strategy initially, opting to avoid feeds altogether after 2 hours 30 or the chop and hanging onto the kayak had any impact? Your thoughts as ever would be greatly received as I’d like to ensure it never happens again.
