I am not sure if anyone out there is training for specific events, or just exercising for fun... but if anyone has a workout to build lactate threshold I'd like to hear it... 

Right now I have a pretty nice bike workout... 20 minute warm-up, then for ten minutes pedal 50 rotations for 30 seconds followed by a thirty second rest (repeat for all ten minutes), followed by a ten minute cool-down.

 If anyone uses something that seems to work (bike, pool, or track) please share
