3 weeks of Training????

Week of 4/5-4/11
Mon 8 mi @ 6:55/mi
Tues 7 mi easy
Wed 5 mi. goal 6x 1mile @5:50 with 2min rest. 5:45(2:00) then my heart rate suddenly jumped to max and I couln't get it to come down. I had to stop the workout and did a full 800 jog/walk to calm it down. I am not sure what happened, this has happened to me a few times over the last 20 years while running and swimming, and I need to remember to ask my doctor on my next yearly physical. I drink way too much cafein, and I hope this is all it is.
Thur off
Fri 13.5 mi, I decided to try wednesday's workout again...in the rain and running in lane 2 on the turns because of puddles. 5:50(2:00)5:45(1:59)5:46(2:00)5:44(2:01)5:44(2:00)5:40 I jogged a 300 on the rests and felt real smooth. I could have been running even faster, given the extra distance on the turns.

I am extreamly frustrated with the last 2 weeks. Mid April is the start of Corn planting for me and the first 10 acres (out of 80) are the most stressful. I can not concentrate on anything else until I get this done. I need to get several pieces of equipment ready and fields ready. All the planting equipment is so specialized that I am the only one who can fix and adjust it, so I can not delegate any of it...Its all on me. I will have all of this done by Today so hopefully I can now move forward with my training, although I have no idea what to do now; Go back to base training or try to pick up the plan where I left off. I guess just getting back to running is a step in the right direction and will help with my general mental attitude. I am sure anyone who has been around me the last few weeks can attest to...I have been a bear to be around.
