My trainer records power, GPS estimates calories burned. Those factors averaged over several workouts along with time and average speed of a given distance all factor into my fitness tracking. Now on race day, I check my resting pulse as it indicates whether I'll have a good day or not. I'd say the resting pulse is vital. Has been a good indicator for all the years I've raced.
