I ran/lumbered a 5k this morning which I enjoyed as I do 2-3 road races per year of varying distances. Now I'm not particularly fast, but I did have a time I was aiming for, which I managed to meet despite the other people I encountered en route.
I know I am being mean spirited, but some of the participants really annoyed me. It is a fantastic effort to complete the race if you are new to running or whatever, but please if you are going to be walking from the very start - as evidenced through lack of running gear and bobbly knitted hat, then start at the back.
Also you get a colour based on the time you think you will take. It's really poor to stand in a faster area as you are holding back those runners.
Equally if you have an injury and aren't able to run, whilst it's great that your partner/friend is supporting you round the course, if you decide to walk slowly two abreast swinging your arms to the side on a tight bit of the course close to the beginning,then you are holding other people up.
Oh and if you are running/walking as a team, again that's fantastic, but you do not need to run/walk all side by side, taking up all the room and stopping people from going past.
Sorry it's a bit of a rant and it is wonderful to see people out, probably as part of their new year resolution to take more exercise, but honestly a bit of consideration would be nice.
