Running plan?

A little history: After a tumultuous year (my geographical move, my oldest child moving out on his own, my youngest child reaching adulthood, my divorce (yeah!), with youngest staying with the ex to finish out school), I've had a hard time sticking with a work out routine. Now, when the spirit is ready, the body is weak. After a visit to the podiatrist, I have Heuter's neuroma in the left foot and a bone spur/plantar fasciitis in the right. I have had cortisone shots, daily shoe inserts, & a nighty splint on my right foot, plus Dr ok to start a training plan for 10K training. (in fact, I think he might show up to the race!)

Don't readily recall where I got this training plan, but I picked it because it was basically a 4 month plan, & stated off very slow (run 10-15 mins) which seemed wise after coming off a "slump" & double injury like I was.

So now question is this: My schedule for Saturday dictates 1.5 mile run. I know, looking at the schedule, that this is to condition me to be my "long run day". This week read (did) like this: Mon: 15-20 min run(21 min/1.6 miles) / Tue: Bike or rest / Wed: 15 - 20 min run(22.15/1.74miles) / Thu: Rest (biked 45.53/8.75 miles) / Fri: Bike or 15 min run (planned rest) / Sat 1.5 mile run / Sun: rest.

Since I'm already running longer distance than the 1.5 miles planned for Saturday's "long run", should I just stick to the 1.5 miles, or plan a 2 miles? (It's my weekend on, Fri/Sat/Sun on, 12 hour day, so will have to get up @ 4am...lol)

Thanks for input! (sorry this is long)
