Yes, spring has sprung. I'm in So Cal, so I've been riding since January, but have enjoyed riding without arm warmers and vest the past two days. Today my friend and I did a lactaid threshold ride. We warmed up for 20 minutes, then pushed as hard as we could for 20, then cooled down for another 20. I did this type of ride with dh once, but this is the first time my friend and I did it together, hopefully the first of many. I'm really seeing a pay off from my interval rides, so starting to add LT rides.
