Transmission transistion

Re-tooling the gear-box to run fast and efficient.
The engine is plenty big enough to do the job, but the transmission has been set on cruise control for the long haul, and that won't get it in the speed races coming up.
To get ready, fast 500's, 400's and 300's, will be injected into the weekly routine.
Today was speed day#1.
1 1/2 mile warm-up.
4 x 400 @71,70,70,70
2 x lead-in 300's @ 55, 57
felt a pain sensation in my right glute on the last 300 so I shut the work-out down to a final 3 mile run. Total of 6 miles
I was pleased with the initial speed session.
