I am training for a 10K-40K-5K duathlon in 4weeks. I pulled a hamstring a few weeks ago. I started back running last week and it seems to be ok but I have been going so slow that I can barely get my HR about 150. I guess alot of is from not training it and maybe fear of pulling it again. I have about 3.5 weeks to go. Would it be best to get in as many runs as possible even if it is slower pace just to get my body back to getting run form back. If so, should I do longer runs? Or just concentrate on cycling and run only a couple of times a week.
