I graduated at the back end of 2012 - not having done the 5k in 30mins. There were lots of people then and now in the same position. I think a prominent sticky, or some such would be a good idea pointing out that 30mins continuous running is an aim of the programme, with the 5k being an added bonus. As has been pointed out many times C25k is just so much more catchy than C230Mins but depending on age, health and possibly other factors the 5k part in 30 mins may never be achievable for some people. Doesn't mean they are not runners or graduates though.
If there is such a beast, sorry. Again though, if there is such a beast then it needs to be more prominent as not many people seem to find it. Also, if this has been raised previously, sorry but I haven't been on the site for a while as I had lots of problems getting back in when the changeover happened.
Mind you my first time on here in 2012 I miis-read some post and thought I had found my way to the C to Twenty Five K site
