According to @HamZa's comment: You could do something like this:

var r = new Regex(@"(\S)(?:\S*(\S))?");
var input = "AAA  AAAAA    AA";
var clusterPositions = r.Matches(input).Cast<Match>()
                        .Select(m => new{start = m.Index, 
                                           end = m.Index + m.Length});
