Big Bike Week Question

Coaches,

I just finished Day 4 of Big Bike Week and am in week 6 of Get Fast Intermediate.  But, tomorrow's weather and family commitments look like I will be limited to 1-2 hours of training, if any.  Should I take a rest day or run or swim tomorrow? Then do Day 5 on Sunday?

Day 1, Day 2, Day 3, Day 4 (cut short due to saddle discomfort).

Thanks,

George
