The exact number fluctuates from year to year; in 2012, it appears that at least 27 Ironman and 8 half ironman races will offer qualifying slots. For example, the intended full Ironman New Zealand was shortened to a half ironman distance due to weather conditions; separately, Ironman 70.3 Japan has been added to provide Asia-Pacific athletes more chances to qualify.
The typical half ironman 70.3 event has 28 to 30 qualifying slots, which, when allocated across age groups, means that you'd probably need to win your division. or at least be in the top 3 finishers, to get that Kona Slot.
