Running 10K in 6 days time

some OF&H updates...

1. I have lost 15lbs since mid April 2012
2. I cycled 17.5miles today - mostly for work
3. I'm running 10k this Sunday
4. I went for a run Wednesday 13/6 = 2.25miles in 32mins
5. I went for a run Saturday 16/6 = 3.3miles in 45mins
6. I did 3 hours of gardening Sunday
7. I swam 20+ lengths @ the Quays (25m per length) - Muts has signed us up for the Southampton triathlon club

I'm still not convinced how my knee will manage the 10k on Sunday... it was fine when i did the Denbie's 10mile run till around the 6mile mark... 
I'll be monitoring it carefully and will walk if necessary.
