Hi topdog, First thanks to all of them who made time to answer. It was an open water swim: My time was 34 min for 1.3 km. At my opinion are my swim workouts very amateuristic : just get to the pool as much as I can and swim, just swim, that is all. This compared to my running where I am in an athletic club, and follow my personal schedule. What do I have to do? Do you have training schedules for swimming? I have 3 to 4 times a week one half an hour time to train swimming, or even a litle more if I leave biking a bit a side. Sorry for my bad English (I do not have time to train that more). Please advice. Bernard PS : Why is my mail disapaered from the newsgroep after less than 24 hours???
