I have the vantage V and it has a race pace feature (might be in the m340 somewhere). I set the distance and the target time pre "race' and it keeps me. Up to date with how I am against the target. It warns if I am not fast enough and tells me how many seconds ahead I am of that's the case. Wonderful feature. Takes away all the mental math and I can just concentrate on the runFor sure, mine tells me my pace and distance (any any number of other parameters if I desire!) Polar m430...
