"My advice to runners whose training is held back by an injury is to focus on what you can do. Eat the right things to heal faster, get the treatment and do the rehab religiously. Pour the frustration into the cross-training and don't forget the power of the mind too. Regularly visualise yourself back from the injury stronger and faster."
Paula Radcliffe never gives up. She's my hero.
And if all else fails, there is always anti-inflammatory gel which is (for me) brilliant. I have taken way too many ibruprofen tablets over the years and this is more topical for when my shit bits start to swell up like a fat kid in a cake shop.
Obvs check with your quack first it's okay to use.
