Q&A #104 - Walking as an alternative to low-intensity running (pros and cons); What training is recommended to when one has a poor anaerobic threshold relative to VO2max? Can walking be used instead of low-intensity runs with similar effect, if heart rate is sufficiently elevated by walking? Possible reasons for a high heart rate even when running easy, and why heart rate isn't everything If your VO2max is high but your threshold power/pace is poor relative to this VO2max, what sort of training is recommended? Possible reasons for poor threshold relative to VO2max, and generally, limited performance capacity at submaximal intensities?
