Here in central europe, there are this tracks made of sawdust which are very soft. Not sure if it is known in the USA. I'm upping my mileage for a fall marathon and I decided that I could do a couple of slow runs (9min/mile) per week on it.
Do you have any recommendation regarding the shoes? I train in Mizuno Wave Inspire and Puma Faas 700, usually on hard surfaces. I don't necessarily need new shoes but I don't want to injury myself.
Thank you.
