Every year, thousands of runners and walkers cross the finish line at the annual springtime running of Mercer Island Rotary’s Half Marathon which includes 10K and 5K races along with a Kids’ Dash, all designed to help raise funds and awareness to fight colon cancer and to benefit an array of other charitable causes supported by the Mercer Island Rotary Club Foundation.
While the 10K race is for runners only, both the 13.1-mile half marathon and the 5K welcome walkers as well as runners. From the starting line on the outskirts of Luther Burbank Park on the northern end of the island, the race unfolds along an out-and-back course that takes a clockwise loop around the island and features a wealth of rolling hills along the way, as well as a few uphill and downhill challenges. The race starts at an elevation of about 75 feet above sea level and dips to a low of about 30 feet in the first mile of the race, which is followed by a gradual climb over the next few miles to about 150 feet above sea level by the time runners reach the 3.5-mile point in the race, along the island’s eastern shore.
This stretch of the race is among its most winding and hilly, as runners make the gradual climb up East Mercer Way, winding left and right as the roadway curves with the shape of the land. Runners stay on East Mercer all the way down to the southern tip of the island, passing through Clarke Beach Park along the way, until East Mercer becomes West Mercer Way. There, runners begin the second half of the race that takes them northward along the western shore, where they can see Seward Park across the lake as they make their way along the winding route.
The race’s biggest hills — as well as its steepest downhill stretches — occur in the second six and a half miles of the race, as runners hit the peak point in the race by about the 9.5-mile point in the race, where the elevation reaches about 225 feet above sea level. After that, it’s mostly downhill (except for another steep hill just as runners are passing through miles 11 to 12) as the race finishes back near the park.

Nice run
Rolling hills on the outside of the Island. Too bad there isn't more view of the water during the run. Could have more photographers. Parking was easier than I expected. MORE

Amazing views, fun hills & great run
Excellent course for 10K and Half marathon with very scenic views, some challenging hills AND the weather always seems to cooperate on race day! MORE

I have actually run this race 4 times, 2011-2014 but decided to combine my reviews all into one since my experience was similar during each of them. Full Disclosure I am also writing this review several years after the race so the race experience may have changed over time however the course has still remained the same.
This was actually the first half marathon I ever ran, and ended up being the first 4 of the over 15 that I have now completed.
EXPO/PARKING: I have never gone to the proper expo for this race and have instead always used the morning of packet pick up option. The day of there isn’t much of an EXPO to speak of but a few things are set up. This has always been no problem and I have easily been able to get into the area and get my packet in mere minutes. Parking has also rarely been an issue although it is a bit of a walk to the race site and I tend to arrive pretty early for a race because I prefer to be relaxed and have lots of time before a race. Most of the parking is in various strip malls near the race site or in surrounding garages although parking was always free.
SWAG: If you run the half you always get a long sleeved tech shirt which is nice. Most of mine look pretty similar just in various colors although one of them is covered in footprints which makes it a unique addition to my collection. Not much else to speak of in the SWAG bag. If you run the 5 or 10k you get a short sleeve shirt. There was no finishers medal in 2011 or 2012, 2013 & 2014 did have ones but they were cheap and flimsy, I’m sure this has improved.
Course/Elevation/Aid Stations: The race starts and ends at the Mercer Island Community Events Center. The start lines up along a driveway that dumps out onto a main road. It can be a little crowded for the first mile or so before people start to spread out. The course essentially just runs around the entire perimeter of the island. You are not running directly on the water but you can see the water through the trees and houses as you run. The trees and crazy expensive houses make for a nice view while you run. After the first mile or so the course narrows down to the right hand lane (water always on your left) which it maintains for the duration of the race aside from a quick use of a greenbelt in the final mile or so to get you back towards the finish. The course is almost all gentle rolling hills and turns. If you have ever driven a mountain road along a river you get a feel for the bendy nature of this road. At the 11 mile mark or so there is a pretty significant hill. Aid Stations are about every 1.5-2 miles (7 total) and have both water and some form of electrolyte drinks, they also give you a Gu packet at around the 7 mile mark. I’m fairly speedy so there is always still liquid available but I haven’t heard friends complain about them running out.
Race Management: This a pretty well run race, especially for the price, (normally <$50 as late as Christmas time). Volunteers were nice and helpful. My only real gripe is as someone decently quick (~1:35 pace) the division of people by expected finish time/pace was not well managed. They have signs up which hopefully would get people sorted where they should be but it feels like many people ignore it and then crowd towards the front which can make the start a bit dangerous and frustrating as you dodge around people, a few of whom are even walking 100 yards into the course.
One other nice thing that I’ve never seen at another race is they have a walking half marathon option that starts 1.5 hours before the runners, dodging the walkers as early as mile 7-8 can be a minor annoyance but having a walking half option is a really nice touch for people who are not quite ready to run one. They also have a kids dash which while I didn’t have children at the time of the race I now really appreciate.

At this race, you’ll find an awesome rolling course that is challenging, but not too challenging, and the weather will be chilly, but not too cold. You’ll be surrounded by other runners who are enthusiastic and friendly. And every year, this race is incredibly well-managed; parking is easy, the course is well marked and there are plenty of water stops, and there are lots of people cheering from their homes along the way. And I’m never disappointed in the technical shirt! For all these reasons, I have run this race multiple times, and will definitely be running it again in the future.
