well, i've trained for it so would be gutted to miss it after all the hard work but on the other hand I don't feel i could even run a mile at the moment. Also, got a nice week on Shetland planned for next week so wouldn't want to be poorly for that either. Will see how the next few days go i guess...
I've just had exactly the same problem but putting in 26/05/2009 as race date instead of 26/04/2009 has solved it. Annoying but at least it's in there now. Good luck with the training everyone!
