How did knights transport their lances, for days and even weeks, prior to battle?

There’s a couple options: 

• If you’re just travelling, you lash it to the side of your horse. 
• Or if you might need it, stirrups were made with a socket that would hold the base of the lance and then you’d hold the lance upright with your non-reins hand. 
• Or if you had a squire with you, they would do one of those two things.
