So let me start by waying that I apologize for apparently being too lazy to write a report for AR50. If you want to know anything about it, just post about it. If you're considering doing it next year, do it, it's a great race, one of my favorites I've ever done.
As for Boston, I hit a 2:53:46 today. My first half was a 1:26:35 and my second half was 1:27:11, so it was pretty even splits. My pace in the 2nd half was actually a bit faster, but I took a huge crap at mile 16 and lost 70-some seconds as a result, putting my 2nd half split a bit slower. My overall pace amounted to 6:37 or 6:38 per mile. I saw it reported both ways and I'm apparently too lazy to figure out what it actually is. I felt pretty good the whole way through and definitely felt like I dropped the hammer throughout the newton hills. I maybe should've gone out a minute or so faster, I think it would've been tolerable. My 2nd half might have been a bit faster, but I felt so good coming out of Heartbreak that I hit mile 22 in 6:02, which definitely caused me to have to slow down a bit from about 22 to 25 until running from 25.2 to 26.2 in 6:10 or something relatively fast. I was pretty happy with my performance, given that it was a bit over a 5 minute PR, though I realized near the end that if I could've shaved less than 2 minutes and gone under 2:52, I would've hit the women's olympic qualifying time for the marathon, which sounds pretty cool, so I'll have to keep that in mind the next time I race. I'm debating racing a marathon next month in May now that I've run a relatively big PR, just to see if I can go faster at this point (I really want to break 2:50 this year and I think it might be possible now given ideal conditions), but I'd have to find a pretty fast course to be willing to commit to doing it since it would interfere with my buildup for summer ultras.
I'll be racing a 10k on Sunday, so it's fortunate that I don't feel beat up whatsoever. After that 10k, if I don't find a marathon for May, I won't be racing again until late June, so I'll be working on hitting pretty high mileage to buildup my endurance again.
