Objectives The objective of the study was to reveal morphology, electrolyte and chosen biochemical parameters in terms of health risk in runners in reference to their age and running speed in the case of running a distance of 100 km, which occur after 12 h or 24 h of recovery. Material and Methods Fourteen experienced, male, amateur, ultra-marathon runners, divided into two age and two speed groups took part in the 100-km run. Blood samples for analyses indexes were collected from the ulnar vein just before the run, after 25 km, 50 km, 75 km and 100 km, as well as 12 h and 24 h after termination of the run. Results The sustained ultramarathon run along with the distance covered (p < 0.05) caused an increase in myoglobin (max 90-fold), bilirubin (max 2.8-fold) and total antioxidant status (max 1.15-fold), which also continued during the recovery. Significant changes in the number of white blood cells were observed with each sequential course and could be associated with muscle damage. The electrolyte showed changes towards slight hyperkalemia, but no changes in natrium and calcium concentrations. There were no significant differences between the age and speed groups for all the parameters after completing the 100-km run as well as after 12 h and 24 h of recovery. Conclusions Considering changes in blood morphology and chosen biochemical parameters in ultra-marathon runners during a 100-km run it can be stated that such an exhausting effort may be dangerous for human health due to metabolic changes and large damage to the organs. Negative metabolic changes are independent of age of an ultramarathon runner and occur both in younger (32±5.33 years) and older participants (50.56±9.7 years). It can be concluded that organ damage and negative metabolic changes during a 100-km run occur similarly in participants less experienced as well as in well trained runners.

Background. Running tourism began to develop along with a growing popularity of running as a form of recreation. The aim of this study was to define the concept of running tourism and to find out the Polish runners’ motives for participation in this form of tourism. Material and methods. The research tool was a questionnaire developed by the authors. It was possible to fill it in during the Cracovia Marathon (04.22.2012) or online; 186 runners answered 20 questions in the detailed part of questionnaire. Results and conclusions. The runners chose the competition venue taking into account the length of the run and the distance from the place of residence. Other important factors were also: attractiveness of the competition, atmosphere and a desire to visit interesting places after participating in the competition. Awareness of running tourism among the runners in Poland is low. The majority of respondents (74%) stated they knew this term, but only 47% of respondents clearly admits participating in it. In Poland the form of running tourism – a guided running tour – does not exist, but it is a niche sector of travel services that has not been developed yet.
