The Oslo Marathon, very well organised by the Sportsklub Vidar, has a new, fast course this year which guides runners not through the hill of Holmenkollen but through the city with all its tourist highlights. The start has been switched from the town hall to the Akerhus Fortress which is another historical "must-see" attraction in Oslo.
After the start, the course passes the new opera house, heads through the historical centre of Oslo and finishes inside the Akershus Fortress.
More than 10,000 participants will run this year - a massive increase on previous years - and organisers are delighted that early registrations suggest more than 50 percent will be women.
The race organiser hopes entries will continue to increase and, in time, the course may have to be changed again. For foreign runners, a course change would be a good reason to return to Oslo and run the Marathon again. Who knows what new, unknown corners and places that they would discover then?
Oslo is the capital of Norway; a pretty city with some wonderful attractions, including the Munch Museum, Vigeland Park and Royal castle. It's a compact city, which makes it possible to get from one end to the other in a very short time.
With Triathlon calendars in central Europe already pointing to next year's events, Elba Island offers long distance specialists great conditions for an end-of-season competition.
This will be the sixth Elbaman Triathlon. A 70.3 event has been added this year and entries have already sold out.
The swim is two laps in the bay of Marina di Campo, a picturesque old fishing village, Participants start from the longest sandy beach on the island to get onto the 3.8km course.
The bike leg is three laps of a 60km course around the western end of the island, on a route offering some magnificent views. It is relatively demanding and includes some steep climbs. Race organisers recommend riders don't use disk wheels due to the heavy wind which is typical for the island at that time of year.
On the running course, some triathletes might think of the Ironman Hawaii as they pass through Marina di Campo with its many palm trees. The route is five loops of a fairly flat 8.55km course.
Elba Island is known as the pearl of the Tuscan Archipelago, just 20km off the coast of Italy. It is an attractive place for all triathletes looking for a very special event at the end of the season.
