Rock climbing is in this year.
The format is a bit of a farce. It's only been given one set of combined medals for 2020, meaning that all entrants have to compete in the three disciplines (bouldering, lead and speed), and the entrant with the lowest score across the three takes home the gold.
Bouldering is short, technical climbing of about 5-10 moves; lead is long, endurance based climbing of about 50 moves; speed is done on a standardized wall and is objectively boring wank that nobody gives a fuck about. Bouldering and lead are related disciplines, and all who do one also do the other, and none of them would normally go near a speed wall. No speed climbers would ever normally compete in lead or bouldering competitions.
What this means is that you'll have a handful of entrants who absolutely smash everyone else at speed, but will take up the last places in lead/boulder while potentially failing to complete more than a couple of moves and looking silly on a global stage. The combined winner will potentially be the lead/bouldering specialist who manages to be the least shit at speed. Most of the big names in the climbing world have had to start training speed, and will never train it again after this summer (speed is being given its own medal for 2024).
Adam Ondra is the best all round climber in the world in terms of outdoor feats, but that doesn't necessarily translate to the often parkour-like style of indoor competition routes. Favourite is probably home athlete Tomoa Narasaki, who has been very impressive over the last couple of years and is also less shit at speed. Janja Garnbret will probably win the women's gold, but the UK has a very strong competitor in Shauna Coxsey who could well come away with a medal.
Anyway, yeah, looking forward to it. Here are the combined finals from the 2019 World Championships if anyone wants a taste.
