Alright, I just got back from a nice LT interval session, getting ready for my 4 mile itt and crit this weekend. I go out to this little "crit course", basically a football shaped course that is slightly downhill for half and slightly uphill for the second, very simular to domigous hill crit this weekend. Well the wind was blowing very hard today, about 30 MPH and that changed things a little. Add to that the 10 miles home is mostly climbing and into the wind...
Normally I do 3 - 4 10 minute LT intervals right at or right above LT then rest for a lap and do it again, it turns out to be 3 laps on 1 off with a sprint at the end. Today the brunt of the wind was going uphill but I refused to let my speed drop under 21 MPH even into the wind on the interval (the other side had no wind but is rolling so it is quite fast (about 27 MPH). I know I was well over LT for all 3 intervals today because of the wind, and after each interval I was absolutly shot. Usually when I do the intervals at just over LT I can do 4 sets of 3 laps and I have almost nothing left after 4. It felt like each interval was just under the intensity for an itt...
Is their any benefit to going significantly over LT in a LT interval for extended periods of time (i.e. like in a race)? Does your lactic acid buffering increase faster when you ride higher above LT?
All I know is the ride back was one of the most painful rides I have done, other than the intervals, going uphill facing a 30+ MPH wind with dead tired legs...
Thanks as always
