How can I see the average pace/heartrate/speed for only a part of my workout?

Problem: When you import a workout as an activity in the diary, TrailRunner displays average and maximum values for speed, heart-rate for the whole workout, but how can you see these values for fixed split intervals or even a selected range like an uphill part only?

Solution: Within the graph, select a range to view the average/maximum values within that range. To get a more precise selection, e.g. to select km 1 to 2 or minute 60 to 90, open the black info panel that is available next to the lower window tools and directly select value ranges using a single-click to select the first value and shift-click to select the end of the selection range.

What is "My Best Performance"

Problem: The diary displays My Best Performance. But that was not my fastest performance. What is it then?
Explanation: My Best Performance is based on the fitness value you achieved. The theory behind that is your most economic run — not necessarily your fastest.
On Fitness: In TrailRunner, the fitness is a calculated value based on the average pace and heart rate of a workout. The idea is that if you where very fast with a low heart rate you are fitter, while the opposite applies if you where very slow and had a high heart rate. This value is just for orientation and does not have the accuracy of the methods used in Polar watches or other biometric methods, but it gives a pretty good overall impression.
