The real races have been in the kids grades. As with the Shaw Baton (and most likely with University Relays) there has been battle in the BU13 grade between Wellington Harriers (20 team points), Trentham United (22 team points) and Wellington Olympic (23 team points). Further back was Hutt Valley Harriers (30) points. This could be the grade to watch for the rest of the XC season.
I doubt that I would run anybody so small over any part of the Vosseler. In the kids race there is a mighty climb from the start line to the road which would seem like a mountain to a tike with short legs.
