I do think the timeline has shifted at some programs and for some recruits, mostly or exclusively the very top tier of national caliber recruits. Some of those did OVs this spring.
I don’t have much first-hand insight into this but my impression is that things haven’t moved forward much for the vast majority of recruits. For most I think things still start to really heat up after state meets junior year and then run through fall and winter.
I’m just basing that on casual conversations at meets this spring, not on any real deep knowledge. But the child of a good friend of ours, very strong recruit graduating from HS this year, was still deciding in Feb of senior year between several top programs. So I don’t think the timeline has shifted forward for everyone or even most.
I’d work a question about process/timeline into discussions with coaches. It’ll probably vary a lot by program and coach.
As far as summer OVs, it might happen at some places but if there’s the option to wait I’d take it. The biggest benefit of OVs is hanging out with the team and experiencing a full campus. Hard to get that in the summer. I do think most coaches prefer seeing how recruits fit with the current team so I’d be surprised if a lot of them prefer summer visits.
Keep in mind the focus for most track coaches right now is regional meets this week, then nationals in a few weeks.
