I just did a half ironman and for my bike leg I felt I paced myself pretty well at an average of 159HR on a pretty flattish course.
The next half in April is on a course which pretty much climbs for the first 45km (the odd dip but essentially reaches the maximum peak of just over 600m around half way) and then more or less downhill for the second half.
Has anyone got any advice on how to pace myself - I guess I should be trying to hit about 170 average in the first 45km (ie flat out) knowing that it will drop once I start downhill given how hard it is to keep your heart rate up. Or save a little on the climb and try to really force it downhill?
As always advice and experience appreciated
