Hi. I'm currently nearing the end of my training for my first marathon (Abingdon on 21 October). I've been following the Higdon Novice 2 Marathon Training Plan.
A couple of weeks ago I did the 18-miler. I planned some walking breaks in there and, despite a bit of a struggle for the last mile, it went OK. When trying to do a short recovery run the following Tuesday, I was struggling to keep my eyes open so I cut it short. I was the same the next Thursday so I didn't run at all. That weekend I came down with a heavy cold.
The cold has gone now but I can't shake off this feeling of overwhelming tiredness. I did a 5-6mi run/walk last Sunday and that was OK (mostly walking though). On Tuesday, I did a steady 5mi run and felt OK after it. Last night though (Thursday) I was back to being completely wiped out. I was going to try and go anyway, but advice from fellow runners on Twitter said I should just rest.
I'm getting a bit panicky now that I'm not going to be ready for the marathon. Training hadn't been going entirely brilliantly before this started, which is why I added in the walk breaks for the 18-miler. With only four weeks to go, I don't know if I should rest completely and hope/trust that what I've done so far will get me round or if I should keep running and try to get some more long runs in before the day.
Thanks for any advice you can offer.
