Splitting rosaries?

[RoughDiamond]

I’m thinking about trying to get 20 of my friends together to each pray a decade of the Rosary every day during Lent. I think I’ve seen this done before, but I don’t remember any specific protocols/rules about it. Does anyone have any experience doing this/any advice?
Thanks in advance!

there aren’t any rules, pray the rosary any way you want. One decade, 5, 15, 20, whatever you have time for.
