Blisters In Ultramarathon [WEBINAR: Southern Lakes Ultra, NZ]

Blisters in ultramarathon - webinar for Southern Lakes Ultra

In this video, I’ll be discussing the impact of blisters in ultramarathon events and how to prepare. We’ll cover things like the gear you’ll need, and what preventive or treatment measures you can take to keep you on your feet in relative comfort til you cross the finish line.

Warning 1: It’s a lengthy video so please see the description for topic shortcuts. Warning 2: Be prepared to see some gory blister photos. While it can come as a shock, it's important to see examples of certain blisters so you can compare them to your blister history and to figure out what you're dealing with.
