The aim of the study is to examine how runners make meaning of digitaltools in the dialogues published on a social networking site (SNS) createdby and for runners who choose to run alone. The study explores the digitaldata generated by the runners using global positioning systems, such as howmany kilometres have been covered, the average pace, the geographicallocation, the total climb, health information related to pulse rate and thenumber of calories burned. Some runners share this kind of data whenpublishing postings on the SNS. The empirical data consists of publishedpostings of visual graphs and photographs with comments in threadsretrieved from the online archives. A transactional approach and practicalepistemology analysis are employed to focus on and analyse the meaningmakingprocesses that are located in the social practices that the runnerscreate when participating online. The participants make meaning of digitaltools (such as sport watches and associated apps) by: (1) sharing detailsabout their running performances, (2) signalling their presence in the socialnetwork of lone runners and (3) planning running events. Digital informationis primarily used to reinforce the runners’ identity formation. The meaningmakingof digital tools thus becomes a way of highlighting an individual’ssocial affinity to a runners’ collective. Surprisingly, lone runners do notuse the performance-related feedback and health information offered bythe digital tools to enhance their running progress when participating inthe SNS.
