I have been perusing HM plans for improvers and am amazed at the different approaches to tempo ie running at HMP. Some say to do only a few miles, and rest easy all week, some have lots of pace work and other speed work. The last one I read has an LSR of 16 miles then two days later doing an 11 miler with EIGHT. At HMP but I cant help thinking if you can do that your planned HMP is too slow?? Any thoughts? What has worked for others? My HM PB is somewhat off the mark as been doing marathon since I last did one and a Recent ten KM would set my HMP at a pace I dont think I could easily trot off eight miles at in training too often.
