I have answered this question about a million times since 2002, the year I went vegan. There are many reasons why a person becomes vegan, from animal rights to health as being the most common.
My reasons aren’t any one thing and it honestly does change from time-to-time. The reason I went vegetarian was for environmental reasons. I went vegan for the same reason. Once I went vegan I realized that I had some sort of lactose intolerance. I haven’t been tested, but for my whole life up to that point I got sick after every meal. My childhood was filled with doctors appointments and illnesses from colds, stomach aches, and even high cholesterol.
When I was 18 years old the doctors wanted to put me on cholesterol-lowering medication. I refused because it was completely ridiculous. After I went vegan my cholesterol got into the normal range and I stopped getting sick. To be perfectly honest I do have some stomach issues that haven’t been resolved. My faith in the medical system is not the greatest and I do a lot of experimentation in my life.
Health is the reason I remain vegan. It just feels better. However, it also lines up with my personal philosophy around all animals being equal. I personally don’t agree with treating animals like commodities and our current agricultural system, especially with animals, is flawed, unsustainable, unfair, and unjust.
Putting it simply, it’s an event consisting of three parts: swim, bike, run. It’s almost always in this order and it always has these three parts. The biggest differences in the triathlons are the distances of the races. Here are some general standard race lengths:
Sprint: 750m swim, 20km bike, 5km run
Olympic: 1500m swim, 40km bike, 10km run
Half Ironman: 2km swim, 90km bike, 21.1km run
Ironman: 3.8km swim, 180km bike, 42.2km run (ie. a full marathon)
Ultraman: a three-day event that totals: 10km swim, 420.2km bike, and 84.3km run
Most races consist of an open-water swim, but some sprints are in a pool depending on the time of year.
