I am also a huge fan of climbing, unfortunately near my hometown there aren't any mountains, so I just stick to bouldering indoor. Watching speed climbing is insane, their speed is so fast and the routes they are climbing are insanely hard. Over the last few years quite a lot of people became interested in climbing, it is even now a competition in olympics. With so many people watching it should be normal to make it also attractive for bookmakers. Top climbers become something like celebrities these days, it would be normal to bet on them.
Yes, climbing will be included on the next olympic games which are going to happen in Tokyo, Japan. That is one of five new sports total which are going to be added to the games, what is also very interesting news for fans of the sport. Actually, so far I have never thought about climbing as a competition, but just as a hobby instead. Anyway it will be really exciting to see the competition soon, probably next month or august.
Since it's official, I'm pretty sure gambling platforms will introduce climbing bets and there will be many people willing to place a bet on it. If I have some spare money I may join as well.
