A plan is being offered to help achieve a sub 18 minute 5K. There are also discussions about what constitutes a good bike for under $5,000 and a study of 5K finish times among 2.2 million runners, which found that less than 2% finished in under 20 minutes. The existence of these separate topics suggests they may be unrelated, or possibly that running and cycling are being considered in the context of overall fitness or athletic goals.
