Ultrarunning is one of the few sports that requires little more than a good pair of running shoes. However depending on the event, some equipment can be essential, especially if one is off the beaten track. At the present time I have no financial interest in the businesses or products listed here. These are either friends or people/products I use or trust and which have helped me in the many multidays I have run. If you feel the same way, send me your recommendations or write to set up your account at mail at multidays.com.
