I have found this to be individual. I know some that just do light training. I know some that cut the volume and do some moderately intense training so they don't feel sluggish by slowing down.
I would take it easy and do a couple moderate, good quality workouts over the next 2-3 days. I only rest one day before a race and sometimes do a light workout the day before. I don't like that stale feeling when I hop on the bike if I rest too long.
x2 on relaxing with some light workouts. I did my first Oly on a Sunday. Worked out lightly that week- did lots of confidence boosting workouts- i.e. fast and flat. I took that Fri completely off and on Sat did a short swim and a 30 min bike. Worked like a charm and I had a great race!!
I do like a short workout the day before because it calms me down and enables me to sleep a little better since I'm not so antsy from not working out. Good luck!!
