OK puncture isn't fixed, can't find the hole at all but old tyres have perished side walls, so new inner tube and new tyres. Managed the first tyre in 6 mins but inflating took 10 mins! 2nd tyre change (to match other one else I know where we will be the same time next week) took a touch longer at 14 mins but included 1 telephone call, him to tell me he is on his way home. so now have 5-10 mins of him changing and 12 miles to get house looking 'better' and kitchen cleaner to hide any evidence that I have just simmered my chain in a pan of oil to clean it (worked really well it is just a real shame I have no pans older than 3 months!) time to reassemble my bike as far as possible and clean before he arrives home ready for his evening meal (yep, same pan).
Did I get my ride in? No.
any inkling of chocies? No.
ah well.
