Ah, that is not good for his long term development. To stay world class and even improve, he has to ride against world class climbers, in world class races.Superman will race in Colombia in 2023. So probably Medellin, unless Savio somehow managed to get him on board.
OK, one domestic year on Colombian CT level won‘t destroy his career. It is better than no racing at all (like during a ban, for example). But he should already begin to start looking for a WT team for 2024.
EF could be a good team for him from 2024 on. They always search for the best South American climbers, so MAL suits well.
MAL‘s last years have been cursed, somehow. Within few years, he had success that made him the day‘s best climber on earth (TdF and Vuelta queen stages!), followed by some really weird, bizarre, absurd stories. That is entertaining, but also (most of all) really sad.
It could have worked so well, with him. He even had improved his weak ITT, at last. He‘s a loss for 2023‘s WT peloton and races. Sad story, but I hope for better years to come, for him.
