Horsetooth 10K-Swimming at Altitude

I've done well at sea level (Boston Light, Potomac River Swim, Lido Key and others), my question is if I show up Friday evening and swim Sunday at the Horsetooth event, how big a challenge will the altitude present considering I'll have virtually no aclimization? Any other flatlanders out there swim Horsetooth? Any lessons to pass on?

    @Ellis of course your personal budget dependent, but might monitor for cheap flights to Denver for June, for a possible training weekend or extended weekend with Colorado Represents Open Water (CROWS) we have a Facebook page. Attend some of our regular training swims and see how you feel and if any training adjustments are needed.

    Thanks Lakespray, my daughter had a similar suggestion. Since my sister has retired to Denver, looks like a visit to the high country is in order.
