15 min warm up at 121 watts x cadence of 90-100 then 5 sets of 4 min x 213 watts with 4 min @ 100 watts & 90-100 cadence for rest periods. Finish with 15 min cool down at 100 watts @ 90-100 cadence. Felt strong and relatively easy except for undulations and shifting winds. Temperature in thr 90’s but it seemed to have zero effect except during cool down phase i dumped a lot of salt. Beginning to experiment with increasing salt - sodium intake to slow down dehydration during super hot and long hours in the saddle days of this time of thr year. By 3rd or 4th set right quad was suddenly not putting in full power - too much lactic built up in it, and right hamstring was trying to pick up the slack, so i backed off a bit to allow the quad to catch up for about 30-40 seconds for it to recover amd it was back to full engagement. I feel amazingly like I used to in my 20’s!
