Best bike split race plan vs Ride with GPS D+ accuracy

Ehh, in this case it would show much more elevation than what the road actually does. My experience with RWGPS is that it smooths the elevation to a point where it’s much much lower than actual.

The other year I looked at RWGPS to determine if a route was going to be good to take my new-ish to cycling wife on for her longest ride ever up that point. RWGPS said that the steepest hill was going to be a couple miles at like 6% with a tiny blip at 9%. Okay, that’s not too bad so we go on the ride.

We turn the corner and it’s like 2km at easily 10-11% average and like 500m at around 15%.

And that’s not the only time it’s done that exact same thing. Strava is usually much more accurate IMO.
