Do any of you know of a good WAVA calculator? I've tried several different ones and they are giving me different answers. :< I am pretty sure I've used this one in the past: http://www.runbayou.com/Wavacalc.htm But it gives me a different top open standard than this one: http://www.howardgrubb.co.uk/athletics/wmalookup06.html So I am confused. (And the reason why is I want to find out what I would have to run this year, to beat a marathon performance I did back in 1999. :)) Thanks! .Terri
