Thanks! I'm not sure where to progress to next with my running. I've slowly built up my mileage over the past 5 or 6 months, and I'm doing between 60 and 70 km a week now. My whole idea was to build slowly, build a big base, and go on from there. Now, the target is IMSA next year, but I took your advice earlier in this thread to "become a runner" seriously, so that's where I'm heading. Currently I do all my running in comfortable zone 2, at 6:00 to 6:20 min/km. As I say, the idea was to slowly build a big base, and then start working on pace. Longest run atm is about 15km, and sometimes I'll do another 5km later in the day to bring the daily total up to 20km. I feel fine after this, and can easily do another 10km first thing next morning. I do about 150 - 180m of climbing in a 10km run. How, and more important when, would you suggest I start doing some speed work? I want to be doing 60 - 70km a week at about 5:00 to 5:15 min/km by the end of September this year - is this feasible? Or should I just keep going at zone 2 for another couple of months and then start doing weekly speed work?
