Contact a sports lab if you're looking for an exact figure. It's never been quite that important to me, but I'll likely do it sometime. I use estimates for training purposes. Anyhow, you can change it with training as well. One of my particular training targets is just that, push that AT up and up.

Short of going to a lab, as Cioccman suggests, doing a time trial is probably the best way. Generally,
average HR attained during a 40k TT is right on to your lactate threshold heart rate; av HR on a
10 mi. TT would be about 103 - 105% LTHR. The same would apply to average power output if
you're measuring power via a power tap hub. For more exact tables for different time trial
distances, consult Joe Friel's Cyclist's Training Bible or Cycling Past Fifty.
