On December 4, I am taking part in HYROX London (men's singles). It will be my second HYROX. After reporting on a number of ex-rugby players who have been diagnosed with the cruel motor neurone disease through my line of work and seen its horrible prevalence in other walks of life, I have decided to try and raise £500 for the MND Association. For those who might not be aware, HYROX is a fitness challenge involving 8km of running interspersed with eight difference specific exercises. In short, it's very tough, especially when taken on without a partner! Any donations to raise money for a worthy cause would be much appreciated. Thanks, Alex Bywater
