400M Repeats

Today was my first 400M repeat workout, it actually went really well and I enjoyed it a lot more than I expected. It was a relatively short workout, but the speed bursts were challenging. I used to do speed work on a treadmill in my previous training plans, 2 min on and 2 min off, this was very similar. The only difference was trying to keep a steady pace, not having the treadmill to set the speed made it difficult. Sometimes I think I miss running on the treadmill... not having to deal with weather factors, clothing, etc. Unfortunately my mindset has changed in that I am starting to feel like treadmill running is kinda like cheating and that I shouldn't really do it. My other problem though is that I'm doing an indoor triathlon soon and I'll have to run on a treadmill for that. My plan is to do some bricks on non-running days, incorporate short runs after spinning and swimming. We'll see how it all goes!
