The 30 minute Grizedale Bike Test- what route?

I’m demo-ing various bikes at the BikeRadar event at Grizedale in April. Each demo slot is 45 minutes, so any suggestions on a repeatable loop of 30 minutes or so to get the most info about each bike would be most welcome. Ideally something with some variety to test as many aspects of each bike as possible?

Cheers all.

climb NFT to Mustard Hill, but go SO a Xroads, not R. Turn R at top of hill, along fire road and rejoin NFT fireroad till it leaves it, at which point go SO and next L down Monk Coniston BW. Turn L at road and climb back up through Lawson Park then down BW (Titty’s track) to VC. Actually, you might struggle to do that in 45 mins, so perhaps go up Scale Green Intake instead of NFT

Crikey 45 mins is a bit stingy – what happens if you take it back late?
