Thanks Debra it was going to be my first ultra so that's disappointing too, but the organisers have deferred my entry until next year so I guess I'll give it a go then. Maybe I'll try a shorter ultra first.
Saw the doctor today. Off work for a fortnight, a week's course of strong antibiotics and some blood tests. Definitely no Ultramarathon at the weekend gutted. I've been training for 6 months for this event and looking forward to it for longer. Oh well. Guess health is more important. It feels like ages since I've been for a run.
