Moving Forward

I would recommend about 16 miles this Saturday, but see if you can get in 3 miles or so (or even 1 for that matter) tonight or this afternoon if you do not have the time for your normal 6 miles.

I would also not recommend a taper before this marathon other than maybe jog 3 miles instead of 6 the day before. Two reasons - a) taper helps only when you have been running enough miles and have done it for a while b) taper is worth it when you have saved enough capital and what to fully cash it out in one race. Based on your 30 K right now you are ready to run about 4:10 - 4:15. You might get a bit of a kick up in fitness from the last couple of weeks which could push it into 4:00 - 4:05 range. So tapered you may run a couple of minutes faster than untapered (which is not always the case, sometimes taper brings out too much pre-race excitement and makes you run worse), but this will affect your preparation for the fall marathon as you will take longer to recover as well from having pushed yourself harder in addition to the loss of fitness from the taper.
