Swindon 10k

[Deleted User]

I am doing 10k run in 4 weeks time . Done Swindon half marathon 2 days ago with a very dissapointing time .Well route was very tough. Took me around 3 hrs to complete .I was never good at running but really started enjoying .Could anyone tell me what will be my rough timing for 10k . I am bit worried as if i come last then more dissapointing . Wants to imrove my running , rather than put off. As I can see people flying pass me .. Any tips welcome .
