5K Updates

I have completed the first three weeks of the Couch to 5K training program. I have 6 weeks left of training and the 5K is 7 weeks away. The runs so far have been challenging but not too bad. This week however, looks like it's going to be tough. I'm a little bit (a lot) nervous, but looking forward to seeing what I can do. My legs have held up pretty well up until the last two runs when I started to notice pain in my knees and calves. Not shin splints, just some joint pains and slight muscle tightness. I probably need a new pair of sneakers but that's not in the budget right now. I'm keeping an eye on it though. I need to stretch more, I know that. Here's my running schedule for week four, I'll complete this run 3 times this week:

5 minute brisk walking warmup
3 minute jog
90 second walk
5 minute jog
2:30 minute walk
3 minutes jog
90 second walk
5 minute run
(18.5 minutes total)
walking cooldown

I'm nervous about the 5 minute intervals. I struggled a little bit with the 3 minute intervals last week but that was due to cramps in my side from my food choices. I hope to do better this week and avoid the side stitches. I know that by the 25th I'll be able to finish 3.2 miles, I just have no idea how long it's going to take!
