I am following this schedule for the next couple weeks and I was trying to shake things up a bit. I need input on whether or not plan A or Plan B makes the most sense. Plan A is 70 minutes monday through friday, 90 minutes on saturday and 65-70 on sunday as a type of recovery day. Plan B is 70 minutes monday through saturday and sunday is 90 minutes. Does it really make a difference? I may be reading too much into this as far as recovery time but I think plan A seems best but if it makes me a better runner I will go with Plan B.
