Gym Closed Early

Man was I bummed out when I went to the gym at 4:00 to find out that the Gym closed early for Thanksgiving.  I was planning to do my lift-bike-run, but had to go home instead.  I rode the bike for 1/2 hour and tried to keep the resistance high.  I cranked up the resistance on the trainer and put it in the big chain ring for 15 min.  My legs really felt it and I got my HR up to the 170s.  After 15 min. I had to crank it down a bit and spent some time in the 140 HR area.  I hope this was an adequate substitution because I am not going to be able to get back in the weight room until Saturday.
