The Power of Your Lap Button
As simple as it sounds, knowing how to use the lap function on your GPS device can have a massive impact on the effectiveness of your training sessions.
Cycle training techniques have evolved significantly in the past decade and a half with coaches such as the late Aldo Sassi, David Bailey and Tim Kerrison implementing interval training sets and targeted climb efforts as part of strategic training plans for the elite cyclists in their squads. As the information about these methods trickles down to the broader cycling community, more and more people are using interval training to improve their cycling performance. My own coaching experiences indicate that whilst most cyclists believe they will improve with interval training, many are confused about some of the basics of conducting interval sessions once out on the bike. The process of developing interval training plans is complex and a topic for another time, but assuming you already have a plan. let's just deal with getting the session done on the road.
Richie Porte who has trained under both Tim Kerrison and David Bailey, has benefited enormously from interval training during his career.
Interval training always involves periods of hard work or intense riding (the interval effort) separated by periods of recovery (easy riding) and it is only the intensity, duration and number of interval efforts that varies from rider to rider. The key to a successful session is controlling the intensity of each effort and sticking to the plan. This intensity is usually set as a power target in watts or a heart rate zone for those who do not have a power meter. It is also useful to note that some intervals may also have a "technical" element attached, such as cadence or pedalling efficiency data, such as Torque Effectiveness (TE) or Pedalling Smoothness (PS). Keeping track of all of this stuff can be difficult, especially when the cloud of fatigue starts to descend. This is precisely what the lap function on your device is for.
The image above shows the data collected on the laps (intervals) during the training session. To the left is the page set up screen for a Wahoo Elemnt. It is easy to select which data will be displayed on the lap page whilst completing your interval efforts
Setting Up Your Device Almost all GPS cycling devices have multiple pages any of which may be displayed at any one time. So it is just a matter of setting up a "lap page" with all of the important information (and none of the "general stuff") displayed. This usually means you will need the following fields displayed:
Your intensity metric, power or HR. If using power be sure to select lap average power and not 3s or 10s power which are too sensitive and make sticking to your number quite difficult. If using HR, it is useful to have fields for BOTH lap average HR and current HR, which will help to keep you close to your target intensity throughout the interval. It is important to record HR data during interval sets, even if you are using power as your primary target. HR is always important during session analysis.
Lap time, so you can keep track of the duration of each effort.
Lap distance in case some of your intervals are distance-based, rather than time-based.
Lap average speed. This can be useful when analysing the data after a session.
Any technical data you may require (or have been asked by your coach to utilise), such as cadence, left/right balance, torque effectiveness or pedal smoothness. Some newer devices will even display information such as force vectors.
Once you have set up your lap page, it is simply a matter of pressing your lap button at the start and end of each interval. This will start a new lap and the data collected will be "refreshed". Now you can simply focus on your targets for that interval. Some devices will automatically default to the lap page when the lap button is pressed, for others you will need to manually select the lap page (by scrolling or pressing a button) before your session starts, then leave it on this page throughout. It is worth noting that you can use this same process for any "segment" of any ride and not just interval sessions. It can be a very useful way of conserving energy during longer rides, or even for pacing yourself during PR attempts at Strava segments. Once you master the lap function of your device, the rest is all about the riding and the effort you put in.
