What are some effective strategies to maintain motivation for winter bike commutes, particularly when the conditions are hazardous, daylight hours are limited, and the cold weather makes it difficult to get out of bed and onto the bike? Are there any mental or physical preparation techniques that can help riders overcome the challenges of winter commuting, or perhaps some equipment or gear recommendations that can make the experience safer and more enjoyable? How do riders who regularly commute in winter find ways to mix up their routes or create new challenges for themselves to stay engaged and motivated during this time? Are there any benefits to incorporating indoor training or cross-training into a winter commuting routine, or can this detract from the mental and physical preparation needed for outdoor riding in cold conditions?
