Does anyone know where I can find a good sports-sized swimming pool near the Asok BTS in Bangkok for swimming laps?

i would say most if not all large hotels in this area have pools,you can usually pay and use the gym or pool in many of them even if you dont stay there

Wana, thanks for your suggestion about the hotels. I noticed a lot of the hotel swimming pools are very nice but are more for leisurely dips than swimming laps. And I wouldn't want to crash into hotel guests lounging in the pool. If there are any suggestions for large, rectangular sports-styled pools specifically for swimming laps, maybe more utilitarian than aesthetics, it would be appreciated.

i assume olympic sized pools would be suitable for hardcore swimmers,rather than people sunbathing on inflateable beds ,there appears to be loads of them in bkk

Try the 25 m pool at Benjasiri Park, next to Emporium, 40 baht membership fee!!!

Great to know, thanks Prudent Rabbit and Wana!
