After lots of deliberation [and lots of advice from everyone on here!] I spent my birthday money on Garmin Forerunner 110 and have to say I'm really pleased with it!
So off I went this morning, having not been for a run for 5 days. Garmin was great, but at Week8, R3 I struggled and ended up slowing down twice and walking for about a min. That said, it was really helpful being able to upload the run on the Garmin Connect site and look at what I did. I realised I'd started off too quickly for the first km and suffered a bit for it. Think I may repeat today's session before I move on to Week 9. Almost at graduation.. but not quite there yet!
