OK, Reykjavik was interesting. It was not my first marathon, but was my smallest. The positives are that is was not crowded, in an interesting city, was a new course without the major double loops, set on a new date to match with cultural festival, and a unique experience. The negatives are having to share the road with traffic, there were very few toliets, were short on crowd support, Coca Cola and Fanta were the energy drinks, and i didnt like running some portions without seeing anyone.

Worth running? Yep, if you set your expectations in advance. This is not the marathon to do if you are looking for support (crowd or race), but is a good experience. At the end of the day, you will have interesting stories to tell.

Very beautiful scenery in this by the sea marathon. But Reykjavik, compared with the number of inhabitants, is a giant city and you are always running in the city. Iceland is so strange and different from any other place of the world. The marathon too, with relatives of the few runners as only spectators. Good drink. Few food. But if you want to make a trip here, you have to run it.
Be prepared with the wind.

I exspected an island nature course, but it was just the not very attractive town area of Reykjavik. After the race I ran a bit through the real island. A fantastic experience, that travel worth. That's why I will return to run first the city and later the country.

Iceland is undoubtedly an interesting country if nature is to be considered.
Not many natives inhabit the island so it is impossible to expect a lot of spectators along the track, which is quite flat and easy to run. Some parts are set along a highway which dulls the overall feeling. The feeling is though balanced with the long distance that you run along the seaside. Many open fields that can be tricky if windy.

In all, flat and nice race. My biggest reward being; to be able to relax after the race at the Blue Lagoon hot spring. Incredibly nice for the legs and feet!!

If you wish to mix marathon with travel and nature - I recommed this strongly. If just for the thrill of a marathon experience maybe another venue is to be recommended.

Fifth of six marathons I've done...two loops which can get real barren, especially when you're low on gas during the second loop...small field and being able to visit Iceland is the main attraction to me...very little crowd support and little control of traffic outside the start/finish is an added challenge...you'll need to be supplied with your own motivation for this especially about 20 miles in when you're running near the water and facing a stiff breeze and falling temperature...was real happy to be crossing the finish line...also when I did this last year the marathon was part of a larger cultural festival and getting seated at a decent restaurant was difficult leading up to the day of the marathon...same problem following the marathon which made for a meal of Big Macs at McDonalds...not the best post-race meal...

thought this would be an exciting and different marathon which it generally was. Traffic control late in the race was bad as I had to run around buses and autos. Pretty seaside setting. Small but enthusiastic crowds. International, small, friendly field. Worth your consideration just as an excuse to visit a beautiful city and country.
