Effectiveness and cost-effectiveness of a 9 week multi-component cycling programme versus an existing single cycling...

Cycling can be beneficial for health, well-being and the environment; however, cycling participation in the UK remains low. Effective and cost-effective strategies are needed to support people in the community to increase cycling. The Cycle Nation Communities randomised controlled trial (RCT) will evaluate whether a 9 week multi-component cycling programme (Cycle Nation) is more effective and cost-effective than an existing national cycle training session on cycling participation, transport use and health and well-being.

This pragmatic, single-blinded, two-arm RCT will recruit ≥268 adults who cycle infrequently. Participants will be randomised to the 9 week multi-component individual/social-level group-based Cycle Nation programme or an existing national standard single group-based cycle training session. Both arms will be delivered by community-based cycling organisations in Glasgow. Participants will complete self-reported measurements at baseline, 12 weeks and 12 months. The primary outcome is the proportion of participants cycling at least weekly at 12 months. Secondary outcomes include proportion of participants cycling at least weekly at 12 weeks; change in weekly number of rides and minutes of cycling and use of private car, taxi, public transport and walking at 12 weeks and 12 months; change in motivation, perceptions of cycling safety, confidence to cycle, self-esteem, vitality, health-related quality of life and perceived general physical health at 12 weeks and 12 months. A within-trial economic evaluation from a National Health Service/personal social service and a broader societal perspective will be undertaken. Pending within-trial results, a long-term model may be developed. An embedded process evaluation will use participant and facilitator interviews, participant acceptability questionnaires, facilitator delivery proforma and session observations.

Ethical approval has been obtained from the University of Glasgow Medical, Veterinary and Life Sciences Ethics Committee (11 April 25). Findings will be published in peer-reviewed journals and communicated to stakeholders and the public.
