I am now training for my 5th marathon in 5 years and I hope to average over 50 miles per week for about 18 weeks. Whilst I enjoy training for marathons I am slightly concerned that I will regret doing so in 20 years time due to worn out knees and hips.
Does anyone know of any scientific studies which assess the long term effects of running on joint health in old age? The general "old wives tale" is that running long distances damages joints. However there are many ex-elite athletes now in their 60's and 70's who don't appear to have suffered any adverse affects.
Does anyone know anyone whose joints have been damaged by running? Are there any othopeadic surgeons out there who have noticed an increase in the number of worn out joints as a result of excessive running.
