It has been a quite a long time since I posted last, but I am in dire need of some advice. I have been doing spin classes and/or my indoor trainer in the winter months. But, I have had the good fortune to go for some rides outdoors the past few weeks. The last 2 rides I have done in the recent weeks is right about 37 miles each. However, right around mile 30'ish, I am experiencing horrible lower bike aches. So much so that the pain runs down my legs. It was mentioned to me that my saddle may be too forward to the bars. Are there other factors that may contribute to this discomfort? I have been riding for the past few years and commute to work in the Summer months (average about 100 miles per week). But these last 2 rides have not been fully enjoyable. Any suggestions are greatly appreciated.
