What is the difference between sprint and Olympic triathlon?

How do I qualify for the IRONMAN World Championship?
Athletes qualify by earning a slot at an IRONMAN-branded qualifying race. Each full IRONMAN event allocates slots to age group winners. The World Championship is held annually in Kailua-Kona, Hawaii.
What are the biggest triathlons in the US?
The SuperTri Chicago Triathlon is the largest single triathlon event with 8,000+ athletes. IRONMAN events in Texas, Florida, Lake Placid, and Arizona draw thousands. Escape From Alcatraz is a bucket-list race. Find them all on RACE.
