D&D 5E - Ashardalon Stride + Haste

Thinking about using Haste (cast by the shield Guardian) plus Ashardalon's Stride upcast at 4th level (cast by bladesinger). My understanding here is the Shield Guardian is the one concentrating on Haste so the bladesinger can concentrate on something else. I think this would give me a move of 130 (30+10bladesong+25Ashardalon's stride=65 doubled for Haste)

I have a bladesinger with a Shield Guardian.

I think this would give me a move of 130 (30+10bladesong+25Ashardalon's stride=65 doubled for Haste) and deal 2d6 to every enemy I walk past. I could also take dash as my haste action to add 65 for 195 while still doing a full action.

Is this a correct reading of this?

Would you allow it as a DM?
