Hi - I'm so happy I found this board! The Disney Marathon will be my 1st marathon (I've done quite a few 1/2s and 10 milers).  I have a training question. I'm following Higdon's senior plan, mainly because  I don't seem to do well running 2 days in a row, and this plan only calls for 3 runs a week.  I've followed his other plans in the past and have had great success with them.  I'm a week ahead of schedule, cause I always build in an extra week in case of illness/injury.  This past weekend I did 16 miles, and felt great! I'm not sure what to do about my extra week. In the past I've repeated the final week of training, and maybe run an extra mile on my long run. I don't know what to do now because his taper for this plan is only 2 weeks.  It calls for the 20 mile run on 12/27. Then 4, 8 and 12 the next week and only 4 miles the final week.   It looks like most people are doing their 20 miler  on 12/20.  Because I'm running less miles than many other plans, do you think a 2 week taper is ok?  I run year round, and completed my last 1/2 in October. 
 
Based on last year's corrals, it looks like I'll be in G.  Thanks!!!
