How realistic is indoor cycling? Climbing the Sa Calobra virtually vs outdoors

Just how realistic is indoor cycling? Whilst Brad was out in Mallorca recently he wanted another crack at going under the half hour on the island's most famous climb, Sa Calobra.

Starting from the north shore of Mallorca in the tiny port of Sa Calobra, the road to Coll dels Reis is 9.4km long and 7% average gradient. Here's the climb on komoot:

You can also ride the climb on a number of cycling platforms, including RGT which has recently become part of the Wahoo family. But how comparable are the two efforts? Is it easier doing it inside, or in real life? We set the climb up as a challenge on RGT, and over 200 people completed it, which gave us lots of data to work with. And how do the two efforts compare? You'll have to watch the vid to find out!
