Cancellation of marathon training/run

I would like to apologise to all the ppl i have asked/persuaded to participate in the Standard chartered marathon. I've decided to draw back on the 42km trainin' and run. This is not an inadvertent decision but due to the injury of my leg, i have to give it a proper rest. The sprain is occurred to ligaments caused by a sudden overstretching. The orthopaedic specialist warned me to rest n no additional force should be applied on site of the sprain for at least 4-6 months. This is to prevent severe sprain which completely tear or rupture a ligament. Another reason is tat i'd most probably be in the States in Dec. I m very sorry for the back out n hereby ask for yr forgiveness. And for those who have already registered, i m sure you'll enjoy yrself with or without me. Lastly, I'd like to wish yr all the best for yr trainin' n actual run.
