Using the Minnesota Gopher sports calendar the dates for the 10K Lakes and Northstar can be whittled down to a few possibilites

Week 1 (3/3/11-3/5/11) Possible Men's BB game, schedule not yet released.
Week 2 (3/10/11-3/12/11) Gymnastics in the Sports Pavillion and potentially WCHA First Round hockey in Mariucci
Week 3 (3/17/11-3/19/11) Big Ten Women's Gymnastics Championship in the Sports Pavillion
Week 4 (3/24/11-3/26/11) Potential NCAA Hockey Regional in Mariucci
Week 5 (3/31/11-4/2/11)
Week 6 (4/7/11-4/8/11)

So weeks 1, 5 and 6 are possible with 5 and 6 being most likely.

Of the remaining two, I think it makes the most sense that they would stick with the same weekend as last year and be Week 5.

Also, at the MN Mentor Forum the possibility of a Week 2 event in Duluth (in addition to the 2 Twin Cities regionals) was mentioned.
