I ran your feed thru Feed Validator, which will display the source code. Line 16 shows:
<link>http://humanpowerperformance.com</link>
Which is a normal line of code. So, I'm not sure what the Podcasts Connect site is showing. However, your feed does have some other issues that are worth looking at. First, there's more than one <image> tag at the top of the feed. iTunes seems to absolutely HATE when this happens. The duplicate and unwanted tag is linking to this file:
http://i2.wp.com/humanpowerperformance.com/wp-content/uploads/2015/10/cropped-LogoGP.png?fit=32%2C32This is probably a favicon image that may have been generated by your WordPress settings. If your theme has a customization section, see if there's an option for "site image" and disable it.
Second, your entry here:
http://humanpowerperformance.com/2016/03/24/clipped-in-bonus-episode/Appears to be putting some characters into the feed that Feed Validator doesn't like. It's in this part:
This is a special bonus episode of Clipped In which features a live recording of the panel discussion from the Clipped In launch party held on March 18, 2016 at Cyclelogik in Ottawa. Big thanks to go out to the featured guests Jeff Leiper, Matt Surch, and David Gazsi. Doug Corner from Bike Race Ottawa also makes an impromptu appearance on the panel to talk about his role in Canadian Road Championships this year in Ottawa.<br />

See if you can get those fixed and try again with Podcasts Connect.
