Today I went downtown by racing-bike in order to buy a nice Erox-Speedsuit (sleevelesslong). It is made out of super-fast drying material and has thicker material at the bottom for biking. Well, it is a pretty good triathlon shop, since the boss always tries the material himself on ironman competitions: http://www.santamonica.ch/index.asp?fun=ent&dest=home&cat111=1 (in German). So he told me also not to forget to drink enough in Indonesia - despite the climate and high humidity. Good hint.
In the evening I went swimming (1 hr./ 1km), although I wasn't motivated at all. However, the swimming-pool turned out to be empty, so that I enjoyed swimming.
