We have a generator in the canteen already...so that's easy...
I know with some race timing software you can run practice timing, that just shows you times as they are posted somehow...pretty sure lapsfree doesn't do this, but I might take a poke around and see what other options there are on this if we'd make good use of it.
I agree timed sessions would be better...but it's only worth the effort of that if enough people come along.
Timing of this is going to depend on access to the laptop and people who know how to run the laptop! Currently myself, Rick and Dan can run it...and Si stores it...it means organising availability between those people to do it...so we all need to get together and figure it out...not totally simple, but not impossible either hopefully.
In the meantime, anyone can make a shout out to arrange a mass practice night (without main laptop timing) for whenever they want. All attendees must be club members though
