I have decided to run the London Parks Half Marathon for Amnesty International. Their work protecting human rights and standing up for those for whom justice would otherwise be denied I have long admired. This challenge is both aimed at getting me fitter but more importantly encouraging contributions to their incredible work.

Recent campaigns include refugee and migrant rights, climate change, children's rights, women's rights, Syrian conflict and LGBTI rights. Amnesty's biggest achievements include outlawing torture, holding war criminals to account and controlling the arms trade.

Your support is of significant value - only together can we continue to make a difference.
