The starting line. Nerves and excitement collide at the starting line flanked by the trees of the park! Photo by Len Villano.

Nicolet Bay, 4 hours to starting horn. When the sun rises over Nicolet Bay, our staff and volunteers have already been hard at work for over an hour.

1 down! At this point, you'll be a half mile from the first aid station.

Eagle Bluff Lighthouse. Eagle Bluff Lighthouse was a light in the dark for sailors for decades. Now it's a landmark for 2,700 runners every May (and a beautiful backdrop for our 1.5-mile aid station. Photo by Dan Eggert.

Tennison Bay. Once past the lighthouse, you'll find the trees clear to your right at Tennison Bay for a beautiful view of Lake Michigan. Photo by Dan Eggert.

Just 10 more now. At mile three the pack will start to separate as the lake and islands are at your right, the bluff to your left, and Blossomberg Cemetery up ahead.

Into the woods. Here the road narrows, creating a beautiful canopy as you enjoy a final flat stretch. Photo by Myles Dannhausen Jr.

The worst hill. Then you make your way to mile 5 and the start of the long climb to Sven's Bluff. Beautiful vistas await at the top, but your legs have to get you there first!

Climbing. The mental games begin. Photo by Dan Eggert.

Everyone's favorite aid station. But once there, the Pirates of the Harbour await - and Jimmy Buffet.

Finally, a downhill! What goes up, must come down, and soon you will. Photo by Dan Eggert.

Having Fun Yet? Few runners have more fun, or feed off the fans, as much as Sister Bay native Matt Burress. Photo by Nate Perry.

The rollers. Near mile 9, the smaller, rolling hills greet you. Photo by Dan Eggert.

Halfway home, almost. Mile 6 brings a welcome relief from the hills... for now...and another aid station soon ahead.

A sound in the woods. Mile 7. At this point you're on a narrow road through a gorgeous stretch of dense woods - and you may just hear a beautiful sound in the distance.

A great place to run

A welcome downhill If you were running alone, this would be your view coming up on mile 6. Photo by Myles Dannhausen Jr.

Spring awakening. When the Door County Half Marathon rolls around each May, Peninsula State Park is coming alive with spring flowers, budding leaves, and the occasional deer. Photo by Dan Eggert.

Breathtaking. If you were to take a break at Sven's Bluff, you'd be rewarded with a heck of a view.

8 Mile. Mile 8 brings a breather before you get to the next batch of hills.

Some 8-mile inspiration. Appropriately, David Cormalath stands on Highland Road, lifting you up as you make the turn toward mile 8 and another aid station. Photo by Nate Perry.

Sometimes, spring comes late. You'll pass the site where dare devils once flew down a ski jump and look out on Nicolet Bay. In the polar vortex of 2014, ice shoves still lines the shore of the bay through late May.

Horseshoe in the rearview. Another view, this time with Horseshoe island in the distance.

Mile 9 and some hills to come.

Fans of all sizes. When you get back to the 6/10 turn, the fans are there to pick you up again! Photo by Nate Perry.

3.1 left! At mile 10, you've got "only" a 5k to go!

Beneath the bluff. And a stretch along side the ravine filled with spring runoff below the bluffs of the Niagara Escarpment. Photo by Dan Eggert.

Doubling back through Tennison Bay. Back at Tennison Bay, another Aid Station a half mile ahead.

Catch a glimpse of Chambers. Chamber's Island in the distance, blue waters everywhere you look.

Past the birches. Coming up on mile 11, runners wind through the marsh to the right and alongside the birch woods to the left. Up ahead, Tennison Bay beckons again.

So, close, now. 1.1 to go! And it's all downhill from here!

A final peak. That's Horseshoe Island in the background. When you see it, you know you're in the homestretch.

Eagle Bluff. Your final view of the water is a great one, with Eagle Bluff and Ephraim across the bay! Photo by Nate Perry.

The finish in sight! That finish line is sooo close!

Faces never so friendly. And the crowd will pull you the rest of the way. Photo by Len Villano.

What's your style? After 13.1 miles, you get to cross the finish line any way you want! Photo by Len Villano.

Accomplishment. And no amount of sweat will stop you from getting a hug. Congrats! Photo by Dan Eggert.

Registration Transfers

Though we are not able to offer refunds for the race due to the fact that most of our costs for staging the race are incurred long before race day (staff costs, medals, and shirts, for example), we are making arrangements to help runners transfer their registration to other individuals.

We do allow participants to switch races, space permitting. Participants may officially transfer a bib to another person, but giving your bib to another participant is forbidden and will result in automatic disqualification. Log into your Race Roster account, click the “transfer” button. You will be able to either switch between the half marathon and 5k; or transfer to another person. You will need the email address of the person you are transferring to, enter that and they will receive an email with instructions on how to complete the transfer.

Transferring between races after April 21, will need to be completed on-site on Friday, May 5 between 1-8pm at packet pickup.

If you need assistance on transferring, please contact Jordan at jordan@peninsulapacers.com.
