Take a terrifying tumble through Lee Valley Park - 10 or 5k, it's up to you - to benefit Parkinson's UK. Or walk. That's cool too. Entry fees are more than resonable - £15 for 5k, £20 for 10k - and organisers suggest aiming to raise at £100 minimum. Advance registration is required on the Parkinson's UK website (link below).
