The Dutch go to CR Prairie's meet the first Saturday of the season. I like Saturday morning meets especially early in the season to avoid some heat issues. They also run a 4K distance for the freshman/sophomores boys if you wish to shorten their first race. This can be helpful for some rookies, while others who are ready for 5K can simply run the JV race.
Just another early season thought, I loved when SE Polk would run their first meet of the year with only one race per gender. Early in the season I think it can be an excellent experience for the entire team to run together and not separate "Varsity" and "Junior Varsity". We are considering this at the Dutch Invitational this season. This can also help possible heat related concerns creating a shorter competition day overall.
