Hey, this is a new feature... We know that there are issues with some of these charts. You may see some big spikes in the middle of some of the charts (phantom hills - we call them) and things like that. We'll be cleaning these up over the next week - looking through each chart, perfecting each one. Until then, take these as good representations of the overall elevation for an event - and actually, they're not too bad, but they'll get even better!
