While stage times are not really the biggest priority it will still be interesting to see how they compare with each other.

It's not an easy pick at all. Petter has shown in Spain that he can be top 5 on gravel. Oliver has had really good speed in Latvia/Estonia but it would be his first time in GB and he must learn and keep it on the road as main priority. So it might be quite close, if I had to pick I'd actually say Petter will be a bit faster.
