I train alone on the bike. It seems to me that a powermeter would be a good tool to ensure that I don't slack off during training rides. For example, I often do six 10 mile intervals (60 mile ride) and feel that I could use the powermeter to make sure I'm hitting my target watts (slowly increasing the watts to gain fitness) during each interval. I don't have the peer pressure (riding with a group) to keep me cranking, so a powermeter would be an honest broker. Are there any reasons why this would not be a good way to use a powermeter to improve fitness on the bike? Several folks have mentioned that they have stopped looking at watts during their ride, so just wondering.
