I know I'm not the only one with this problem. The first time I tried a cycling class, the instructor helped me get my feet, clad in borrowed cycling shoes, attached to the pedals. The second time, I was on my own, and spent two full songs smushing my feet against the pedals in the dark and praying for some kind of miracle.

If you only do one of the sports in a triathlon -- swimming, cycling, or running -- you're safe for now. But as soon as you take up a second, a thought begins to sprout in the back of your mind. What if I did a triathlon? it whispers. I would only have to learn one more thing.

Sharing your running and cycling routes is the whole point of using Strava - you can see whether you're the fastest in your neighbourhood at climbing that big hill, or take on a friend's favourite running route to see how you compare. But this weekend, Australian analyst Nathan Ruser pointed out that the app's heatmap of popular routes reveals, oops, data about military bases and the people who are stationed there.

Cyclists take to the streets to get to work, to get fit or purely because it feels great to ride a bike. But boy, do they cop a hiding from motorists. As a South Aussie-expat, this time of year is notorious for one thing: In the shadow of the Tour Down Under, cyclists take over the roads, footpath and cafes.

Here's a list of commandments you should be following if you want to avoid getting a filthy spray from an indignant motorist.

Ready to try a group cycling class? You'll need to set up your bike and learn how to connect your shoes, but once you're in the saddle the instructor will tell you exactly how to work your butt off. Here's what you need to know for your first time.

This week we're tackling the topic of urban cycling. Our guests include Eben Weiss, author of The Ultimate Bicycle Owner's Manual: The Universal Guide to Bikes, Riding, and Everything for Beginner and Seasoned Cyclists; Rosemary Bolich, the Director of Community Outreach at We Bike NYC; and Doug Gordon, better known as Brooklyn Spoke - a TV producer and outspoken cycling advocate.

Bike sharing giants ofo has chosen Adelaide as their first Australian city as the company seeks to expand their footprint into the southern hemisphere. The bikes use GPS-enabled geofence technology which guides users to park bikes within the current area in which ofo is operating and where the pre-determined preferred parking zones are located.

Walking is a great way to explore a new city because you can get up close and personal. On the other hand, driving lets you explore spots that are out of reach by foot. If you want a happy medium between those two options, look into bike tours.

If your city doesn't have bike lanes, it's up to every car that passes you on your bike to determine how much space to give you. Despite tough new passing laws in some states, they often still suck at it. Cyclist Warren Huska solved this by strapping a pool noodle to his bike.

You don't need a gym or even a running track to build your cardio fitness. Just a few flights of stairs can do the trick, if you have a good plan to work from. These routines from Fallout Fitness fit the bill.

If you're a cyclist, there's a good chance you've thought about getting a GPS cycling computer so you can see mountains of data at a glance and you don't destroy your phone's battery every time you track your rides. The Garmin Edge 520 and Wahoo Elemnt are two of the newest, most forward-thinking options available, so let's see how they compare.
