These metrics may seem relatively low when looking at our training plans compared to some online recommendations. Why is that? There are two main reasons:
1. The swim workouts aren't included in your weekly planned TSS until you've completed and uploaded the workouts. This can make the TSS and CTL scores appear lower than they are in reality.
2. The CTL score is based on a moving average of your TSS over the previous four weeks, weighted most heavily towards the previous 7 days. My plans have a recovery week every fourth week, which will effect the CTL score (making it seem lower). However, 20+ years of training, competing and coaching have shown this method to be extremely effective, especially for amateur athletes.
