The last couple of years I've been averaging 6-12 marathons a year. Recovery drinks are one of the things that seem to make a difference for me. I used R4 (orange flavor) for a while but it always made me excessively gassy and would rack up my stomach for the next couple of hours. I even mixed it in a portable mixer to make sure I didn't have any dry lumps and experimented with watering it down. Nothing worked and I finally gave up on it. I've found my body likes the PowerBar Recovery drink better. No more gas and gurgling after drinking it vs. R4. I believe in the science behind R4, it's just some ingredient they use that doesn't agree with me.
Marmot makes some great clothes and the DriClime Catalyst is no exception. I simply love this jacket. It's thin, light, allows freedom of movement and breathes really well. Fit wise, I'm 5"10"/155 lbs. & the Medium fits perfectly. I originally bought the DriClime Windshirt to wear while running in colder weather, and while it performed well, I found I missed hand pockets (the Windshirt only comes with a chest pocket). I searched some more and discovered the Catalyst jacket made out of the same material. In addition to the hand pockets I've found that the neck and hem drawstrings allow me to use the jacket in colder weather. I've run along a river trail in breezy 15 degree weather wearing only a short sleeve technical shirt underneather the jacket and remained toasty warm inside (yet, the jacket's so thin!). The best feature of the jacket is how well it breathes. I sweat at a pretty healthy rate once I'm warmed up and this jacket does a great job at dumping all that perspiration while not allowing the wind to chill me. If I start to overheat, I open a couple of zippers, loosen the drawstrings and the heat dissipates rapidly. I can't say enough good things about this jacket. It's my new favorite piece of clothing, so much so I bought a 2nd one in a different color.
The Windshirt is a great windbreaker that breathes well. It's incredibly light and thin with a full zipper, a chest pocket and elastic cuffs. It has a 2 inch slit on each side to allow for greater freedom of movement. I bought one based on the reviews here. I was looking for something to wear in colder weather on my longer runs of 10-20 miles. I've run along the river in gusty winds and 25 degrees with only a short sleeve technical shirt underneath and the windshirt has kept me warm. For that purpose, it's worked out well, it's just not as versatile as I'd like. For $20 more, the Marmot DriClime Catalyst Jacket has additional features that are well worth the extra money. (At this writing the windshirt retails for $89, the Catalyst for $109, less on SAC). With the Catalyst you get hand pockets, and neck and hem drawcords, allowing you to use it in colder weather, with the same breathability. The Windshirt is a great piece of apparel, the jacket just has a wider range of use.
