Stick with Amazon, had my 405cx for 11 months, started showing signs of corrosion on charging contacts. I rang Amazon and they issued a replacement free of charge on express delivery. Had done over 1100km with it too. Now I have a brand new watch with another 12 months guarantee. Winner. Can't fault Amazon for customer service.
Entered this as my first marathon after missing London ballott. Huge United fan so may be a blessing in disguise. Done two HM's this year in just under 1:24. Aiming for sub 3 on first marathon. Too ambitious? Is there a staggerred start at Manchester based on estimated finish or is it a free for all?
Did it last year as my first ever 10k, smallish event just over 100 runners, was able to sign up on the day no issues. A good mix of abilities from good club standard runners to fun runners. The course is run on country lanes, a frying pan shaped route - out along the 'handle' for 1km, a 8km loop and back along the 'handle' to finish, that's if they keep the same route. It was slightly down hill for the first 4ish km then undulating for the rest with a ford to cross after about 8km and one sharp climb for about 600m. Organisation was good, easy parking right by start, small village hall type building for sign up and briefing, cold water in cups once finished. Overall a good event, not a PB course but a nice run with decent scenary. Hope that helps, may see you there.
