2022 All Stars Summary:

What a day for competition, community, camaraderie, and fun on Sunday at Redwood High School! In a challenging year, Tidalwaves met the challenge to host a revival of an old MSL All Star meet format.

In a nod to the strength and meaning of the 50-year plus, all volunteer run, larger Marin Swim League community, for this one day of the season, the swimmers weren’t members of each of their ten teams but were instead members of either the evenly matched Blue team or White team. Excitement and fun filled the air and the pool as the swimmers found their friends from around the league assigned to their team for the day.

As with all MSL meets, the swimming was superb, the volunteering nothing short of inspirational, the coaching applaudable, and the community comradery uplifting!

Yes, the swimming was just as fast, with exactly 200 best times swum, 3 pool records broken, and a final score of Blue Team 1025.5 and White Team 1107.5. A Tidalwave of thanks to John Nolan and Jessica Harrison for leading this outstanding effort!
