My husband has recently started biking again and has one non-insulated plastic water bottle from the local bike store. When he put a cold tap water/ice cube combo in this bottle it was melted in less than half an hour. I was hoping for advice about the following questions:
1) Is cold water better or worse than room temperature water when biking distances of 20-30 miles?
2) What recommendations would you have for insulated water bottles and why?
Thank you for your advice,
