Hi, I have just bought a Triax C10 and I am liking it too much.

I have a question, although, on setting training intervals.

C10 has only 5 different intervals, but I would like to set up a
training with only 4:
- On the first interval I would like to make a 30min with heart rate
between 137bpm and 150bpm;
- Then, on the second interval I would like a 10min to recovery
(100bpm to 136bpm)
- Again other interval like the first, 30min between 137bpm to 150bpm;
- And finally, the fourth interval would be similar to the second with
10min in 100-136bpm.

I follwed the steps in the manual, but I can only put the interval of
time or the threshold for the recovery heart rate. Is it possible to
include box time and heart rate zone in C10? How does this threshold
works? The manual says "This number acts as a recovery heart rate. The
segment will not work if your recent heart rate is less than the set
value", but I did not understand. Can anyone explain that to me, please?

Thanks for the help.
