If unofficial official practice started yesterday, what was all the practicing (and missing O-training ;-) ) you had been doing up until now?
The training before this week wasn't announced for outdoor track, and only people who REALLY wanted to be competitive in outdoor, and for people who wanted to run indoor knew about, and attended those practices.
There are various state regulations on how far before the season "official" practices start. Coaches can start "conditioning" earlier but aren't allowed to make it mandatory or to do any actual "coaching". Schools and coaches stretch these limits to varying degrees; in many places it is simply understood that if you want to be on the team, you will come from the first day of conditioning. But most coaches (I think Dylan's is included) stay within the rules. And in Dylan's case, indoor and outdoor track have different seasons, with indoor being earlier.
Such is why orienteering works best in schools as a "club" sport...
