Question for the forum hive mind: is ten minutes to change train at Leeds sufficient when one is encumbered with bike?
Make sure you have a train app on your phone which shows the arrival & departure platforms. That way, if you check your arriving train say about 10 minutes, before you're due in Leeds and also your next one, it gives you a heads-up of the likely way you might have to dash.
But assuming the first train isn't late, then 10 minutes is fine. However, don't faff waiting for a lift if you need to get onto a different part of the station - carry the bike up/down stairs.
