5.5 miles (8.85 km) each way, very flat urban/suburban mix. Takes me about 20 minutes.

On my last commute, I did a 9 mile commute in 50 minutes over mostly flat road. Now, my commute is just under 2 miles but takes me 25 minutes over roads that are nothing but hills.

Just over three miles at just over 12 mph average including a half-dozen stops at intersections.

I have an 11 mile commute. 4 miles is gravel road, sometimes somewhat washboarded, but not terrible. The rest is paved. There are a dozen or so short hills, perhaps 40 feet of rise/drop on each. SE Michigan glacial holes, for those familiar.

In warm weather my average is about 16.5 MPH. I have made nearly 18 on really good days.

I just checked my comp, and this morning my avg was 13.9 MPH, at 13*F, the gravel road section was only mildly rutted. The worst I have done is last week after heavy snows, there was some rutting that nearly dumped me several times and really slowed me down, and the temp was -3*F; my avg then was 13.6 MPH.

On the way to work (9.5 miles) I average 17.5 mph. On the way home it is around 14.2 mph. Uphill on the way home, obviously.

By the way, I just bought a jacket from Performance last week, and really saw a slow down at high speeds. Talk about wind resistance, and this is just a thin shell, in my size! Places where I can go 30 mph with a jersey and armwarmers are near 26-27 with the jacket!

I go 22 Km each way. Have to start work early and so I'm pedalling by 6am. In the morning with not much traffic, average about 23 km/h on a standard Trek touring bike. Slower if I use my mountain bike which I do if I'm going to the pool after work (I think its less attractive to thieves). Lucky to average 20 km/h on the return - lots of hills and intersections.

5 miles, 20 minutes. Includes stop signs and traffic lights. Today I overslept and made it in 12 minutes. :)

I am a freelance photographer, so the commutes vary daily. most are 10 to 20km one way.
the commutes are mostly flat area, but my average speed according to velo 8 cateye, never exceeds 20km/h.
I am slow, aren't I ?

My commute is 7.5 miles in the morning and 10 miles in the afternoon. It takes me 35 minutes in the AM and 55 in the PM. It is a mix of average hills, extended inclines and flat road. I take a more direct route in the mornings and travel through more residential areas in the afternoon.

5.1km one way. 21km/hr in cold temps.

My average is about 15mph in the winter/wind and goes up to about 17 or 18 in the summer. This is for a 4 mile ride but I can normally keep the same pace for up to 2 hours then it starts to drop.

12 mph TO work (more uphill)

13 mph FROM work

that's door to door, all stopping, lights, etc

I was averaging 11 mph by my computer. That was on my mountain bike with 1.4 richey slicks.

Then about six months ago I bought a seatpost-mountable carrier for my old Fuji road bike and began flying the six mile route to work. I'll never go back to commuting on the mt bike.

The best commute was 68 kilometers and took 3.5 hours roundtrip for a speed of 19.3 KPH

Just about 10 miles, and about 30-35 minutes going in, and right around 55 mins coming home, which is mostly uphill.

3 miles in about 12 min on the way in (downhill) and and 15-20 min on the way home (uphill). I'm on a mtn bike with slicks.

I travel approx. 15 to 18 miles one way pending on the route i take. I travel between 18to25 mph (all flat ground,except for 2 overpasses) stopping for lights & such , it takes me around an 1hr10min. to make it to the shop on a MTB.

13 miles exactly one way, 30-40 minutes on average depending on how hard I push, usually around 35 minutes though. Pretty flat, 50% rural road, 50% 4 lane divided highway (with a huge shoulder).

I'm excited to see where my next job takes me, can't wait to plan out a new commute wherever I end up.

My commute was about 24 miles one way. I would drive about 12 miles to the bike path and start from there. My fastest time was 1 hour and 6 minutes. Somewhere around 21 mph. Now I only live 8 miles from work but I got some hills. I haven't rode to work yet, still too cold in the morning.

Over my 8.5mi totally flat commute between 20-21mph average moving time. 19-20mph elapsed time (i.e including stop time at lights)
When I was riding faster in April-05 I hit 23mph auto average, 22mph elapsed a few times.

Just as an aside over the past 22 months of commuting I just calculated I've spent a total of 27 hours and 24 minutes stopped at red lights.

I've found for the flat route I ride (this is different for everyone due to terrain, number of lights, turns, etc.) that my average is about 4mph less than my steady state cruising speed between lights and turns.

I have a 4.4 mile one-way commute with some lights. On the way out, it is 1% downhill plus a couple of overpasses and has some easy right turns. The best I have managed on my 25 yr old Centurion is 18.4mph, but a more typical speed is about 17-17.4mph. On the way back, with left turns and all that, my best has been 14.9mph, but typically I end up with 13.5-14.0mph. The speeds were the average speed readings taken at the end of the ride off my Astrale 8 computer which has an auto-start/stop function.

My 14 mile each-way commute takes me 1 hour and 15 minutes. I ride through downtown DC, and do such things as stop at red lights (!)

My commute is about 5.5 miles (9 km) and takes about 35 minutes coming in; 30 minutes going home. Thats with 20 stoplights and stop signs each way, so average speed is somewhat higher.

i dont have a computer on my slick tire mtb but the other day i was commuting with a friend riding a vespa he told me to ride as fast as i could and he would drive at even speed and told me i was going 20mph , i told him his speedometer was probobly a little off so i probobly ride somewhere inbetween 13-18 when i get crazy.

i dont have a defined commute route but when ride i like tours within 3 - 10 miles depending on my mood.
