Here's how one Running community member has maintained her half-marathon training while injured.
In the midst of my training for my first-ever half marathon, I've been suffering from posterior tibial tendonitis, which can be very painful to run with, due to the amount of impact. But I've been rehabbing my injury with lots of great tricks that my physical therapists have turned me on to. One of them is the Alter-G Anti-Gravity Treadmill, which offers precise levels of partial weight-bearing so that athletes can train with less pressure on their joints. Usually, I run for 30 minutes on the Alter-G at 70 percent weight, which I suppose is what it would feel like if I were running 30 pounds lighter. It's not as simple as it sounds: Because you're not at normal weight bearing, you have less control when running, which means you need to use more core strength when running to keep everything tight and together. Still, when I'm running on it, I don't feel any pain — and it's easy to run much faster than normal. Lots of fun, and a great way to build back your cardiovascular and running strength when bouncing back from injury!
Whether you're just starting the Couch to 5k program for beginners or are logging miles training for a marathon, the AlterG Anti-Gravity Treadmill can help in a big way.
