No; they don't tend to broadcast them live - though they did in 2018, in Lenzerheide. I did see a clip of the start on Instagram; and noticed Laura Stigger, and Ronja EIbl are racing the U23, after racing the Elites in World Cups & Olympics.
Strangely, in 2019, Eibl was probably the best U23 rider - and she was racing against Stigger, Richards & Lecomte; not sure what has happened to her.
Eibl had a missed season last year after suffering from overtraining when the season resumed after the covid break.
This year has been decent in her first full season racing the Elites world cup, fighting for the top10s.
But Stigger and Mona are generational talents, they will be XCO legends in their primes, I have no doubt about that.
