I am registered for the TOT 13K. We just completed a 10K yesterday and my DH wants to register for the marathon in January. Has anyone gotten ready in such a short time? I am petrified of being swept (is this normal for the first time?). My pace for the 10K averaged to 13.1 but that's only 6 miles, not 26! I know DH can accomplish it but I'm concerned about myself. Any suggestions?
