Training for any of the Seven Summits challenge requires a range of skill, endurance, strength & resilience. For many of the peaks, preparation included regular weekend hikes accompanied by weekday gym work. For the Antarctica 2013 and Everest 2014 expeditions, work started years in advance of the climbs. This page takes a look at the specific preparation undertaken by Paul at University of Limerick ahead of Antarctica 2013 & Everest 2014 to help provide an insight into some of the preparation needed to attempt a high altitude expedition.

Training at UL focussed on Strength, Endurance, Hiking, Alpine Skills and Altitude Adaptation as well as utilising in-house Sports Science to assess progress through VO2max testing, DXA Body Scanning and Blood Tests at specific intervals. A unique aspect of Paul's training was the opportunity to live full-time in the National Altitude Training Facility (Altitude House) on the University of Limerick campus for over a year, spending 14-16 hours per day in simulated altitude (hypoxic) conditions. This state-of-the-art facility is the only one of its kind in Ireland and UK and offers the complete hypoxic living environment for athletes and mountaineers alike.


Preparation for Everest 2014 included 2000 hours spent in simulated altitude conditions at the National Altitude Training Centre from July 2013 to March 2014, coupled with a specific schedule of training (2x per day) and long periods at the weekends spent hiking the hills of Kerry, Tipperary and Limerick with heavy loads. The University of Limerick based facility is the only residential altitude training centre in Ireland and UK, providing elite sports people simulated altitude conditions while also availing of the world-class sports facilities on campus at UL. Paul spent an average of 14-16 hours per day living in simulated altitude created by the filtering of air entering the house and the dumping overboard of most of the oxygen until the mix of oxygen-nitrogen is equivalent to the desired altitude.

Altitude living was complimented by Altitude Training at the nearby Delta Sports Dome in Limerick, complete with state-of-the-art Altitude Gym where the public can train at altitude. Training in the altitude gym was twice-weekly and involved cardio sessions with and without the backpack, usually interval-structured to heighten heart rate and test my capabilities in sustaining blood oxygen levels while undergoing high physical demand at altitudes up to 4000m.

Everest sits at 29,035ft or 8848m, with the summit sitting in the jet stream and in a zone of significantly reduced air. When your body is exposed to “thin air”, it compensates for reduced oxygen levels by increasing the bloods oxygen-carrying capacity, as well as its ability to use that oxygen. By living in the Altitude House and training at an Altitude Gym, my body is forced to adapt to these thin air environments as follows…

- Increasing red blood cell mass for delivering oxygen to muscle cells and converting it into energy.
- An increase in V02 max (the maximum amount of oxygen the body can convert to work) giving me more stamina for the long haul.
- Cranking-up hematocrit levels to provide a greater percentage of cells carrying oxygen.
- Elevating capillary volume, creating more blood pathways to muscle cells for improved muscle oxygenation.
- Increasing the volume of mitochondria – the powerhouses in cells that help the body turn oxygen into energy.
- Increasing the lungs’ ability to exchange gases efficiently – so that for every breath taken, more oxygen gets into the bloodstream.

These changes result in greater aerobic capacity (VO2 max), greater anaerobic capacity (the body’s ability for explosive performance) and improved endurance – meaning faster speeds at a given exertion level. The aim of living and training in simulated altitude conditions was to improve adaptation to all of the above. This does not enable you to zoom up the mountain on arrival, but gives you a head start in terms of the natural adaptation. It does not simulate the hyperbaric or pressure effect of altitude, so is not a substitute for time spent on the mountain during the preparation period of the expedition. Instead it supplements that preparation in giving you an additional string to your bow in the preparation stakes.

Working with the Physical Education and Sports Science (PESS) Department at University of Limerick, Paul took part in testing to help validate the physical and hypoxic preparation for Everest. A team of experts at UL helped him to best understand how data derived from a range of tests can help to inform and validate training with inputs from the following...

Daily SaO2, hydration and heart rate tracking

- DXA Body Composition Scans
- Blood Tests at regular intervals
- VO2max 'Bruce Protocol' Testing

For the 2014 & 2015 Everest expeditions, a team of specialists supported Paul during his 26-week training program at University of Limerick. This team consisted of Rachel Turner (Altitude trainer), Aidan O'Keefe (Endurance trainer), Jackie Doherty (Strength trainer) and Paulette Egan (Yoga instructor). I am greatly indebted to this team for their hard work and dedication towards the mission. 


Weekly training involved 15-20 hours of physical activity, split between strength, endurance, altitude work and hiking/biking. A typical week included the following mixture of strength, endurance, altitude adaptation and overall conditioning to provide the best possible chance of being physically and mentally prepared for the challenge of Everest. The image above gives a sense of the quantity of training completed in the final 6 month period prior to Everest.

2 Strength sessions - Upper and Lower body
2 Endurance sessions - Boxing/TRX/Sled
2 Altitude Gym session - Treadmill work at 4000m
2 Stairmaster sessions in gym
2 Ladder practice sessions (using boots and crampons)
1 Yoga session - Focus on visualisation and breathing
1 hiking day - Typically 6-8 hour day with 25kg backpack

The journey to Everest started in September 2012 and included a number of significant physical preparation milestones that Paul set for himself along the way to challenge and test readiness in advance of the big climb. The timeline also included ice climbing training, advanced Alpine skills training in Alps in 2013 along with solo climb of Mt. Blanc and a range of other Alpine peaks that same year, culminating in the completion of the 6th Summit (Mount Vinson in Antarctica) in January 2014. The preparation then continued and intensified in the run up to Everest in April 2014, with regular long-day treks with the University of Limerick outdoor pursuits club. Image below shows a mixture of hill trekking, ice climbing, alpine training, running, cycling, personal training, altitude training and altitude living in the months leading up to departure to Everest. It is also punctuated by assessments (Bloods, VO2max, DXA Body Scans) to utilise Sports Science to help better inform training zones and needs along the way.
