I wouldnt run with a laptop - they dont like it. If you desperately need exercise you could cycle in ?
The laptop should be ok. If it can take speed bumps, rubish road surfaces and other bumping around whilst I am on my motorbike then it should be fine
I really need to build up my running miles. The only time I get to go out is first thing in the morning and I really don't fancy getting up any earlier to fit more miles in.
I am looking at changing my hours at work so I can go out in the evenings instead but I can not do anything until my son changes schools in September.
Cycle in London! In my opinion you need to be slightly mental to want to do this. Everyone I have spoken to that has or does cycle has had an accident. With the route I would need to take there is no cycle path option other than for 1/2 mile.
