More difficult than it’s always been?
vtm showed brico cross free last weekend. They tend to for a clump of smaller races.
Most world cups have been on uci channel.
eurosport player shows the cross live even if the highlights are on only on E1 or 2 later.
Hooky Feeds come and go over the year but you can normally get something through cyclingfans for live stuff. Full replays tend to be harder.
