4+ hours in the saddle is too much for me in the virtual world. the last time i did that it was the 4 horsemen in zwift. i cannot image doing 4+ hours. yesterday i rode one of the Davos Swiss challenge rides in rouvy, came in at 2 hours 45 minutes. that was enough for me. 12 mins slower than last year. only 35 miles though. i had been three days out of the saddle and i can feel it in my legs now.
nice job by the way.
