I've recently severely damaged the ligaments on my big toe, and can barely walk and have been advised that it is likely to take at least 6 weeks before I can run on it again. 

Unfortunately, this accident has happened whilst I'm training for a marathon at the end of September. I was ticking off 15 mile runs quite happily before the accident, but I'm at a point where I can barely stand for more than a few minutes: Certainly no weight can go through the toes on my damaged foot. The toe is still incredibly painful so shoes are out of the question and until the nail comes off, I think swimming is off the list too.

So, in light of this, do you have any suggestions as to what sort of activities might be beneficial for me to still take part in the race later in the year (assuming everything heals up nicely)?

Thanks
