A couple of readers have been confused by my reference to "No. 2 toilet stop", thinking I had more than one toilet break. Sorry, this is an English expression to mean my one toilet stop was of the type that is best not executed in a standing position.
For anybody who has me on Bloglines, it appears that the feed may have been broken since I switched to beta (grr), so you might have to re-subscribe.
Thanks again for all the encouraging comments. I am still quite content with the result. One thing I haven't mentioned yet, as I don't want to make excuses, is that I am not sure that I went into the race at 100% health. I don't know whether it is nutritional or a low-level virus or something, but somehow I just haven't felt quite 100% in the week or so leading into the race and still now. Toilet function was also not great and alternated between too much and too little, shall we say (as testified by the stoppage during the race). I have no idea if any of that contributed to my legs conking out, but it is possible.
My legs have had surprisingly little soreness since the race and I managed a slowish 6 km yesterday without much drama. My legs did mention towards the end that that was far enough.
