To people that do both: Are Mtb's that much harder (haven't been on it for 5+ months) or am I really that pathetic?
Yes, I'd say climbing on a MTB is harder due to the uneven surface for a few reasons:
- Losing traction with the rear wheel when trying to push makes it hard to keep the momentum going.
- Having to increase your effort to lift the front wheel over roots/bumps/etc makes it harder to keep a steady pace like you can on a road.
- Off road paths can be steeper gradients than you'd ever get on a road
