Do you know which site supports the athletics?
How to bet on this sport after all? What strategies are the best? Does it make sense to bet on the events with dozens of participants?
Is it by and large popular on any of the markets?
If I'm not mistaken, most of the platforms don't have IAAF World Championship in its offer. Correct me if I'm wrong.
Gambling companies tend to focus more on popular sports. If the World Athletics Championships is popular around the world or in a country many gambling companies will most likely include them. By the way, these kind of sports are not played often.
