W5R3 is a nice run, most people are surprised to find they can actually do it. That's when you really believe you can graduate because once you know you can get from 0 to 20 minutes in 5 weeks, going from 20 to 30 in another 4 weeks doesn't seem quite so scary any more But Oldfloss is right, the first two runs of week 6 can be a shock if you're not ready for them - people think they'll be easy just because they have walking breaks but what week 5 shows is that you've reached a stage where the walking breaks are no longer make that big a difference. If you take it as seriously as today though you'll be fine. Most folk seem to find the challenge from this point on becomes more mental than physical.
