Thank you both! I'm starting to get a bit nervous, but am determined to enjoy it 
Had my last chiro treatment and sports massage, last run yesterday, carb loading is in full swing (starting to feel like Regina in Mean Girls "biscuits/croissants/cupcake frosting are carbs, right?") and will pack my bag tonight. All that's left is to run the thing!
Not sure if I'll get a chance to come back online until after the race, so if I don't - everyone have a great weekend!
Make sure you all take it easy, no sneaking in one last long run (too many of my friends have done this ahead of Brighton and now have all kinds of scary niggles that require physio tape and prayers to get them round).
