<p><span style="font-size:medium;"><span style="font-family:'times new roman';">I have a marathon coming up in early November. While I’m ahead of schedule, I do have a minor complication. I signed up for a ½ in October, and then another ½ I had entered for September was rescheduled for October because of flooding – so I now have half marathons on consecutive weeks in October, 3 and 4 weeks before my marathon. I’ve already done three 20-milers in training, and would like to fit one more in. My question is whether it would be better to do my last 20-miler 5 weeks before the marathon, or 2 weeks – which I fear may be cutting it close. Any advice?</span></span></p>
