10.5 miles in. most of it on a state hwy, medium/light traffic. then a frontage road that has a nice, big decline where i hit my top speed of 38mph. 35-45 mins
8.5 miles home on another state hwy, high traffic. 30-40mins

unfortunately atlanta doesn't have the best road system for cycling...so I have to ride about 4 miles to the subway, then take the subway to a station right across from my office.

I'm trying my best to find a way to get to a farther away station to up it to about 10 miles each way

28 in the morning. 17 in the afternoon. I take a bus to shorten the trip.
I may start throwing in 1 or 2 days a week of 28 in and 28 back. Still working on that idea.

My ride is 7.5 miles each way. I ride from the East end (upper beaches for those that know) down to south Chinatown in Toronto. Takes me about 30 mins in, 45mins-1hr back home - the ride home going back up the hills that I come down in the morning.

I only ride in a max. of 3 times a week so far, the uphill and against-the-wind factors (particularly riding across the lakeshore) really seem to bog me down in terms of my muscle recovery / tiredness levels, etc.

I maintain (according to my tripcomputer) an average of anything from 12-15mph, I don't go all out but those big hills that I used to be discouraged by don't seem nearly as bad now after a few weeks of riding in. My actual 'cruise' speeds are more like 16-20mph, typically hovering around 18 though.

I'm 25 and working to get/stay in at least some 'reasonable' shape. I sweat like a person who sweats a lot, so I found a local-to-work gym with reasonable membership rates that I was able to use for my showering, as it's absolutely necessary for me and my overactive glands..

What I find myself doing on the trip home is taking an extra 20-30 mins to stop off here and there and admire some of the lesser-known/seen parks or little alcoves near the lake just to relax by, I love this part of my day and look forward to it each time I ride in.

My ride to classes and work is four miles each way. It takes about 20 minutes at my normal pace, as little as 16 if I push hard, and up to 25 if I take it real easy. Starting the day after tomorrow, my commute will become drastically shorter - maybe two thirds or three quarters of a mile. Moving is a pain, but it does have its perks!

Riding less is a perk?

16 miles takes me about 1 hour and 15 minutes.

2.85 each way. Takes about 10-12mins. I singlespeed though and need to get a much bigger gear.

11 miles each way ... previously I was riding a 9 mile route with many long hills and lots o' traffic, until a friendly (rare around these parts - most MD cyclists won't respond to a nod) fellow cyclist showed and rode with me a new route (thanX Josh!) The new route takes me about 40 +/- minutes. The 2 extra miles doesn't make much of a difference, except my AVG MPH is better!
Also, check that those boasting 20 MPH AVG probably don't have many hills - LOL.

6.7 Miles there and ?? back. I will find out tonight how long the return trip is seeing as today was my maiden commute. ! hr left and I cant wait to get out there and ride. I will take a different route homw due to the sadistic San Francisco geography.

19 miles AM, about 90 minutes
9 miles PM, about 45 minutes, depends on Gail (high winds)

Jeff, still a bit of a fat biker

3.2 miles eachway.
- job's moving +/- 8/15/6 so commute will change to 13.0 miles each way (45 mins x2?).
- right now 15 mins gets me to/from, on average!

Before starting my new job I was riding 8k's/5 miles each way. Now it is all of 3k's/2 miles. Because it is so short I have added a rear fender to the MTB and bought some rain gear so I don't have to drive at all unless there is something else that needs to get done that day. I haven't driven to work in over 3 weeks.

My ride is 21 miles each way. Speed averages about 14 mph riding an old diamondbak apex w/slicks.

41 miles round trip. It takes me aprox. an hour and a half one way.

There are far too many variables. The main one is probably the traffic situation: how much traffic is there on the roads, how frequent are intersections with red lights, how bad are the traffic jams? The second most important variable is the terrain: is it flat or hilly, or all downhill, or all uphill? Then your physical condition is important, but I think anyone who doesn't just consider 25 miles an impossible distance to ride is in good enough physical shape to ride it in a decent amount of time. The type of bike you have might make some difference.

If you have luck on your side (i.e., if you can find a good route with few stops and relatively flat terrain), you'll probably be able to make it in 1.5 hrs under normal conditions. A couple of problems are these however:

1) You'll probably need some time to park your bike, clean up and change unless your job is like mine (I teach cycling right now - yay! - so I work in the clothes I wear on my commute and parking a bike means just rolling it into the room we're based in anyway).
2) If you ever get any sort of problem such as a flat tire - you'll be late.

30 mph average is not fast, eh?.. Um, I hate to be the one to break this to you, but we're in a cycling forum, not motorcycling!

My commute is 11 miles in, 11 miles out. I make the trip (door to door) in 40-45 minutes, and that includes several stop lights. My average speed is 15.9 mph for this trip, which includes good and bad days on a cyclocross bike.

If you have a road bike, relatively flat terrain, and few stops, I think 1.5 hrs would be reasonable.

16 Miles each way. 1hr 5min in, if traffic agrees, 1hr 15 home. Home is where the hills are. Speed is about 14-15 depending. Sometime head winds are large as I ride along a river and there is often times a substantial head wind

22 to and from. 1:10-15 to, :55-1:05 home.

Add in a couple more for lunch trips and on occassion when I feel abusive another 25 for a jaunt up to Boulder for a long lunch.

9 each way. about 40 minutes to work, 35 back. My commute's a "bowl" shape, with a steeper grade TO work.

All side streets, light medium traffic but slow, and cross a few busy streets en route. Been doing it for 6 years, and one thing I like is the predictability. My commute has never taken me MORE than 45 minutes even with wind, or less than 35. I always know exactly what time I'll get home, traffic is not a factor at all.

I wear shorts/t shirt (warm under armour gear in winter), and keep some shirts and pants at work.

all the best! definetely try it. once you get used to it you'll find it's a wonderful way to break up your day, whether you're racing fast, or just putting along enjoying the scenery. (I do both depending on my mood)

Cripes! Those are some spiffy times
I so want my racing bike. 28 miles takes me 1:45 on a touring bike.

+1 what Chephy said. I have had 5 mile routes I could do in 20 minutes easily, and now have a 13.5 mile route that takes me 1 hour despite being a much stronger cyclist than I was when I had the 5 mile commute. Hills, traffic lights, stop signs, etc all will change how long it takes you. The only way to know is to go out and ride it. A test ride on the weekend is a good barometer for how long you should budget. Traffic changes during the week, but the impacts of those changes on cyclists tend to be relatively minimal.

inja- You riding the capital crescent now? I too live in silver spring, but find the 4 mile cutover to bethesda more than worthwhile for the improved ride down the cct.

fryth - One of those MD cyclists who waves.

My commute is 14.2 miles to work, 15.7 miles home (I use a different route because of traffic flows). I average between 15 and 17mph, depending on how hard I push. I shower, dress and have breakfast after arriving at work, and shower again when I get home.

0.6 miles in, 1 minute
0.8 miles home, 6 minutes
