I'm getting a bit frustrated now. Across various threads you go round the houses for the same topic.
You can swim breast stroke if you want to.
Some others have said they have swum breast stroke.
However, these are likely to be the exception, not the rule. For proof, go on YouTube and look for clips of triathlon swims. Look at Outlaw, any Ironman event. Look for ITU championships. People are swimming front crawl.
Most people swim triathlons front crawl. That's the fact of the matter.
Please stop fannying around looking for positive reinforcement and instead go back to improving your front crawl at Tri club swims. Yes, you might be scared but just bloody well get on with it.
At Lichfield, swim breast stroke if you want because you are still learning crawl but when you are training now you should do crawl. By next summer, you will be much improved.
fairycakes, are you a hot person or a cold person? Last year I had a big dilemma over kit and made the wrong choices (for me) and got really cold. It's mid September in West Wales and the temperature potentially drops over the next couple of weeks. In my mind, it's an autumnal race.
I got cold coming out of the water and getting onto the bike in wet kit that then had to dry off whilst on me, drawing my body heat. I had on tri shorts and a tri top and put a bike jersey over the top. Obviously I was wet, so the jersey just got wet! Out on the bike I saw many DNF athletes in just tri suits wrapped up in foil blankets. I ended up putting my rain jacket on, not because it was raining, but because I was cold. Although it rained later! Fortunately, I did have more clothes for the run and changed into 3/4 tights (I was really cold by this point) and another clean bike jersey. As the weather continued to deteriorate I ended up with a jacket over the top of that jersey. (I'm a back of the packer, finishing in 16 hours in the rain).
If I were taking part this year and the weather was as autumnal as last year, I would go for a full change (at least of top half) in T1 just to get dry clothes on and be warmer. Probably a jersey and arm warmers with a jacket in my pocket. I'd probably include another top for the run and include 3/4 length tights in case I was cold. If I wasn't cold/wet coming off the bike, I may not use any of it.
That said, if you are warm blooded, like Seren, you may not have the same concerns. Seren probably doesn't have the same memories of being cold as I do.
