Running while traveling can help you build or maintain physical fitness, and prepare for competition. Some people complete marathons or other races all over the world, either as part of visit to a place they wanted to visit, or as the main reason for going there. Companies such as Marathon Tours and Travel operates tours that take traveling marathoners around the globe.

Marathons, endurance races and shorter distance runs are held in many cities and some rural areas at all tines of the year.

• Hash House Harriers. This is a running club that originated among expats in South-East Asia, but has spread widely, with well over a thousand groups in many countries. They do a weekly hare-and-hounds run, followed by a gathering at a local eatery. There are frequent regional gatherings called "interhashes". They are sometimes described as "a drinking club with a running problem".  

Guided running tours

Guided running tours are a fairly new category of adventure travel. Experienced local running guides take clients on great routes and allow them to maintain a running routine while travelling on business or pleasure. They are known as "running tours", "city running" or "sightrunning". Generally, we can distinguish two kinds of running tours. Scheduled tours are such events that take place with fixed time, itinerary and meeting points; more than one participant usually takes part. Most popular are the customized, private or personalized tours which only realize once a traveling runner books them. Some providers operate both kinds, especially the established or bigger ones; some specialize only on customized tours.

Internationally, there are nearly 200 running tour organizations. Most of them operate independently. On RunningTours.Net you can find almost 100 independent and well-rated running tour organisations around the world. The organisations on this network website mostly started 5 to 10 years ago and have the best quality/price rating.

Global Running Tours successor, Go Running Tours networks dozens of sightrunning providers on four continents. With roots in Barcelona's Running Tours Barcelona and Copenhagen's Running Copenhagen, it was quickly joined by Running Tours Prague based in Prague and others. It focuses on bringing quality standards into the field of activities with quite a few requirements (insurance, top customer rating etc.) for a provider to fulfill before they are invited onto the board. In The Netherlands, you can find running tour organisations in a.o. Amsterdam, Nijmegen, on the National Parc the Veluwe, Rotterdam with Rotterdam Sight running Tours and in Maastricht Maastricht Running Tours.
