Clean way to reduce many TimeSpans into fewer, average TimeSpans?

Question

I have a C# Queue<TimeSpan> containing 500 elements.

I need to reduce those into 50 elements by taking groups of 10 TimeSpans and selecting their average.

Is there a clean way to do this? I'm thinking LINQ will help, but I can't figure out a clean way. Any ideas?

I would use the Chunk function and a loop.

foreach(var set in source.ToList().Chunk(10)){
    target.Enqueue(TimeSpan.FromMilliseconds(
                            set.Average(t => t.TotalMilliseconds)));
}

Chunk is part of my standard helper library. http://clrextensions.codeplex.com/
